Penny: I got a little residual check from my commercial, and I thought, hey, how about I get the guys a little thank you to pay them back? So, Sheldon… (pulls toy out of bag) ta-daa!
Sheldon: (gasps) A vintage mint-in-box 1975 Mego Star Trek Transporter with real transporter action! Hotdarn!
Leonard: (awestruck) Where did you get that?
Penny: That's from Stuart at the comic book store.
Leonard: You went to the comic book store by yourself?
Penny: Yeah, it was fun. I walked in and two different guys got asthma attacks. Felt pretty good.
