Sheldon: Oh, Shelly? A man's here to take you away to the future. Be sure to pack clean underwear.
Penny: That's good. That's good. That's good.
Sheldon: Mommy, why are you crying? 'cause I'm gonna miss you, Shelly-bean, even though you creep the bejeezus out of me.
Penny: Okay, I guess we're improvising now.
Sheldon: Well I'm sorry. It's not my fault. I'm just incredibly smart, and everyone around here is dumber than a bag of rocks. Oh, now, don’t you start crying. You get in that spaceship. Mommy's late for Indian bingo.
