Are we watching a TV series or visiting San Diego Comic-Con? Talk about a who’s who of geek royalty. Welcome to and today we’ll be counting down our picks for the Top 10 Big Bang Theory Guest Stars.

For this list, we’re taking a look at the most memorable guest stars that have appeared on this CBS sitcom.

#10: Steve Wozniak

Considering much of this show’s humor revolves around tech, it was only a matter of time until Apple co-founder Steve Wozniak dropped by. The gang encounters the Great and Powerful Woz at the Cheesecake Factory. Sheldon, who has decided to live his life through a mobile virtual presence device, can’t resist saying hello. Wozniak is impressed with Sheldon’s robot and even offers to sign his 1977 Apple II. Sheldon rushes to deliver the computer to his 15th favorite technological visionary, but sadly trips going down the stairs. The Apple II breaks and Sheldon hurts his ankle. The cameo may have been brief, but it was unexpected, funny, memorable… and an excuse to hear soft kitty!

#9: Bob Newhart

Despite being a television legend, Bob Newhart had never won an Emmy until he appeared on “The Big Bang Theory.” In 2013, he took home a well-deserved Outstanding Guest Actor award for his performance as Arthur Jeffries, aka Professor Proton. The former host of a science TV show, Arthur is taken aback when Sheldon and Leonard hire him to perform at their apartment. Although he’s reluctant, Arthur evolves into something of a father figure for Sheldon. The character might’ve passed away towards the end of Season 7, but he still occasionally appears in Sheldon’s dreams as a Jedi Master. Arthur offers sage-like advice, which is only made funnier by Newhart’s trademark deadpan delivery.

#8: LeVar Burton

This “Star Trek: The Next Generation” actor has made a few fun cameos over the years. First, when Sheldon invites Burton to a party, he actually shows up. Of course, he immediately leaves upon seeing the state of things. Thankfully, Burton would later return as a guest on Sheldon’s online video series, “Fun with Flags,” only to be criticized by Amy. In season 8, Sheldon invites Burton back, and Burton accepts, albeit with one condition. Sheldon then proceeds to show him his George Washington Carver impersonation, and later asks Burton to dress as a swastika. Between Sheldon and Troy from “Community,” LeVar should probably stop meeting his biggest fans, however hilarious the results may be.

#7: George Takei

Another “Star Trek” alumnus, George Takei unexpectedly pops up in Howard’s sexual fantasy. Although Howard’s sexual orientation is briefly questioned, Takei and Katee Sackhoff help him to realize that it’s ex-girlfriend Bernadette he truly harbors feelings for. After Howard wins Bernie back, Takei and Sackhoff resurface. Sackhoff tells Howard to make the move, but Takei advises him to take things slowly - and despite being interested in men, Takei seemingly know a thing or two about romancing the ladies. We’ve got to say that, platonically speaking, Takei and Sackhoff have serious chemistry. Any chance of them getting their own spin-off? That’s a series sure to have audiences saying, “Oh my!”

#6: Carrie Fisher

Hitting the town with James Earl Jones, Sheldon arrives at Carrie Fisher’s house. Ringing her doorbell, Jones and Sheldon make a run for it. Armed with a bat, Fisher answers the door to find nobody there. It’s clearly not the first time he’s pulled this routine. Now… the idea of Darth Vader ding-dong ditching Princess Leia is downright hilarious, but what makes this moment especially noteworthy, however, is that Fisher and Jones had astonishingly never met before. While they both had key roles in “Star Wars,” Fisher performed on a set while Jones recorded all his lines in a sound booth. Leave it to Sheldon to finally bring two sci-fi legends together.

#5: Wil Wheaton

Of all the “Star Trek” actors that have appeared on the show, Wil Wheaton has got to be the most memorable. This is largely due to his ongoing rivalry with Sheldon. Wheaton became Sheldon’s mortal enemy after he missed a sci-fi convention in 1995. Sheldon’s hatred for Wheaton only grows stronger after he tricks him into losing a card game. Becoming one of the show’s funniest recurring antagonists, Wheaton would go on to troll Sheldon for the next couple years. He finally makes peace, however, by giving him a Wesley Crusher action figure. Since then, Wheaton has continued to show his friendly side. Just don’t tell him that “Star Wars” is better than “Star Trek.”

#4: Katee Sackhoff

Before joining forces with Takei in the aforementioned episode, this “Battlestar Galactica” actress served as Howard’s fantasy - although for a fantasy, she was pretty effective at shooting him down. Appearing naked in Howard’s bathtub, Sackhoff not only acts as a great comedic foil for Howard, but despite being make believe, serves as a real voice of reason. She tells the lonely fanboy that he needs to stop dreaming about fictional characters and acknowledge the real girl in his life. As if that’s not enough to kill the mood, Mrs. Wolowitz interrupts and causes Katee to disappear. Frak!

#3: Stan Lee

Anyone who’s seen a Marvel movie knows that Stan Lee is no stranger to epic cameos. There’s only one word to describe his cameo on “The Big Bang Theory” however, and that’s “excelsior.” Sheldon isn’t at all pleased when he misses an opportunity to meet Stan The Man, so, with some help from Penny, Sheldon finds Lee’s house. Answering the door in a “Fantastic Four” bathrobe, the comic book legend feels, understandably, that his personal space has been invaded. Beyond irritated, Lee sarcastically invites them to come inside and Sheldon, as oblivious to social cues as ever, accepts. Instead of an autograph, he goes home with a restraining order!

#2: James Earl Jones

On any given occasion, Sheldon Cooper is easily the most unpredictable person in the room. After crossing paths with James Earl Jones, though, Sheldon suddenly becomes the stable man. At first feigning annoyance, Jones quickly takes a liking to Sheldon. Bonding over their mutual love of “Star Wars,” Jones takes Sheldon to a carnival, a karaoke bar, and a spa. Even Sheldon is mystified by Jones’ eccentric behavior, and eventually grows weary of iconic actor’s attention. Before seeing this episode, we never would’ve pegged Jones as a party animal either, but now we’ll never look at Darth Vader the same way again, that’s for sure.

Before we get to our top pick, here are a few honorable mentions:

Summer Glau

Bill Nye

Buzz Aldrin

#1: Stephen Hawking

It IS called “The Big Bang Theory” after all, so it should come as little surprise that for series co-creator Bill Prady, Stephen Hawking was always a “dream guest star.” In season 5 however, it became a reality, when Sheldon got to meet the world’s most famous theoretical physicist. While Hawking is happy to meet Sheldon, he does point out an embarrassing error in his thesis. Adopting a hilarious on-screen persona across a few episodes, Hawking proves to a skilled, albeit kind-hearted troll - feigning having a big ego and mocking Sheldon, but also taking the time to wish him a happy birthday. It turns out that he’s not only brilliant, but seriously funny too.
