Quote from Joey in The One with Phoebe's Uterus
Joey: So, what job did you get, Joey?
Joey: Tour guide at the museum. Ross got it for me.
Rachel: Well, how can you be tour guide? Don't you have to be a dinosaur expert or something?
Joey: Not really. They give you all the information. It's like memorizing a script. And on your left you have a tyrannosaurus rex, a carnivore from the Jurassic Period.
Chandler: Very nice.
Ross: Yeah, actually, Joey, it's the Cretaceous Period.
Joey: Yeah, but I can pronounce Jurassic.
