Chandler: So, what job did you get, Joe?
Joey: Oh, ah... tour guide at the museum. Yeah, Ross got it for me.
Rachel: Well, how can you be a tour guide? Don't you have to be a dinosaur expert or something...?
Joey: No, not really. They give you all the information... It's, uh... it's like memorizing a script. (speaking like a tour guide) "And on your left, you have Tyrannosaurus Rex, a carnivore from the Jurassic period".
Chandler, Monica, & Rachel: Hey! Great! Very nice!
Ross: Uh, actually Joey... it's the "Cretaceous" period.
Joey: Yeah, but I can pronounce "Jurassic".
