Big Bang Theory Quote
(Penny walks in on Sheldon having his nails done by Ramona)
Ramona: Dr. Cooper is working.
Sheldon: Yes, I'm close to a breakthrough. Oh, tickles!
Penny: (leaving the apartment) Holy crap on a cracker!
Leonard: (meeting Penny in hallway) Hey, Penny.
Penny: You probably don't want to go in there.
Leonard: Why? What are they doing?
Penny: The only way I could explain it would be in a therapist's office with dolls.
