oh and another one:
mr k (when hearing a fish singing): "whos playing squidwards records?"
yet another one:
(after seeing squidward with krabby patties on his head) "so, you finally got that hairpiece"
ANOTHER one:
(after getting his dollar back): "me and blue lips (i forgot what he called it) settled on a trade."
sb: "what did you give him?"
krabs: *jumps on the boat with half his body missing* "nothing important"
