*Sarah and Jane are having a coffee together. Cindy walks by and says hello*

Cindy: Hey loser, how's life being the tubbiest girl in town?
Sarah: Better than having the ugliest face in town.
Cindy: Coming to Steve's party tonight, or weren't you invited?
Sarah: Actually it's Tom's party, if he'd invited you himself, you would have known!
Cindy: Oh wonderful! See you tonight girls!
