It's also been a plot hole with how old Dr. Zoidberg is, considering how he knew Farnsworth as a Full Grown Decapodian since the 2920s, and of he's really that old then the tar that made the Planet Express Crew younger would've made him older then a Teenager.
In flashbacks we saw Fry's old Pizza Delivery Boss Mr. Panuchi age, even Jrrr has aged.

Christmas Trees had gone extinct by the events of Futurama as shown in Christmas Episodes where Xmas Trees are now Palm Trees, but other episodes show Pine Trees, for instance with those set in the Forest.

He's had Good Luck plenty of times without a Clover throughout the series, aside from the Comic Reliefness that Cartoon Characters like him are known for.
