Penny: Sheldon, I can't believe you got us a wedding gift.
Sheldon: I don't know why you're so surprised. I watch movies. I see what people do.
Leonard: What is this?
Sheldon: Plane tickets and hotel reservations for a weekend away in San Francisco.
Penny: That is so great!
Sheldon: Yeah, there's fisherman's wharf, and Alcatraz, and cable cars. We're gonna have so much fun.
Sheldon: Is there a problem?
Penny: Uh, no, no. I just said "Weeee!"
