Betty: Did you enjoy the party last night, Rob?

Rob: Yes, but I drank too much and I upchucked all night long.

Betty: So did I!!! I was blowing lunch until two o'clock this morning.

Rob: I'm sure I swallowed some barf meat.

Betty: Did it taste good?

Rob: Hell NO, bitch! What kind of pervert do you think I am?

Betty: Oh, I don't think you're a pervert, dude. I only asked because the baloney sandwich I had for lunch yesterday tasted better when I was tossing the toenails earlier this morning.
