Skipper: This isn't a catastrophe! It's a catastratunity!
Kowalski: A catastratunity?
Skipper:Catastratunity! Beautiful word!
Kowalski: Catastratun-ity?
Skipper: Catastratunity!
Kowalski: You just made that up!
Skipper: Cat-as-tra-tun-ity!
Kowalski: Oh, catastratunity, yeah, yes I've heard that word before, many times! *backs away in fear*

This is one of my personal favourites!
