Kara: Okay, look. I'm flattered, but I'm not going to marry you, Mxyzptlk.
Mxyzptlk: You know it's funny. I'm all seeing and all powerful, but that's one of the few things I can't make you do. That and make you fall in love with me, and/or stop you from killing yourself, and/or make you drink orange juice for some reason.
