Oh I've got a lot but they're hard to remember so here are the ones I can think of right now...
(Timmy becomes invisible) Timmy: Cool, आप can see right through me! Wanda: You're 10. You're not that hard to read
(When they travel back in time) Wanda: Look आप were still in you're mommy's tummy. Cosmo: Wait, I thought she loved Timmy. Why would she eat him?
Wanda: आप bet me for a nickel! Cosmo: But it was a shinny nickel!
(refering to himself and Wanda) Cosmo: We're two halfs of a whole idiot!
Cosmo: If I don't make it, stay away from my wife. Anti-Cosmo: And if I do make it, take mine
Timmy: आप brought him here too! Wanda: Well when आप made the wish आप कहा "we" Cosmo: and "we could mean anything. We three, we the people, या my प्रिय Weeeeeeeeeee!
