Howard: Then simply sit, spin, stand, stretch. Maybe in looser pants. Then step, grab, tiny pivot, pull, and you're there. (sighs) Easy, peasy, mac and (exhales) ... you get the idea.

Howard: So you can never take it (the sweater) off?
Leonard: No.
Raj: Not even to sleep?

Bernadette: I've been seeing him for years. I'm still not convinced he's real.
