Big Bang Theory Quote
Sheldon: (after he gets to the bottom floor, he's surprised to see Penny there after he just left her and Leonard) How did you get down here?
Penny: The elevator. It's really fast.
Sheldon: I-I need to be alone right now. Don't try to follow me.
Penny: (Follows him) All right. You need a ride?
Sheldon: That'd be great. Thank you.
