Ducky(looking over Petrie's shoulder as he is drawing something): What's that you're drawing Petrie?
Petrie: A liger.
Ducky: What's a liger?
Petrie: It's pretty much my favorite animal, prefered for skills in magic.
(When Petrie and Little Foot are talking about girls)
Little Foot: Chicks dig guys with skills!
Petrie: What do you mean?
Little Foot: You know like, num-chuck skills, computer hacking skills...
