There's something fun about quoting the cut scenes. Mostly because practically no one knows what the heck you are talking about.
"You're getting a little soft in the city."
"You've got a mouth bigger than a meteor crater."
"It looks like Wormie's got too much sun!"
Or if you want to get really obscure, which I do sometimes, is start quoting lines out of the earlier drafts of the scripts:
"I'm a free-booter, not a revolutionary. You're aboard the wrong ship, son!"
