Penny:
Question one: Given the choice of anyone in the world, whom would you want as a dinner guest?

Sheldon Cooper:
Hmm. Living or dead?

Penny:
Just says "anyone in the world." Guess that means living.

Sheldon Cooper:
Oh, that's just as well. As much as I'd love to meet Euclid, inventor of the geometric proof, he probably wore sandals, and I cannot look at toes during dinner. Oh, I know! The person I'd most like to have dinner with is myself.

Penny:
You sure that's your choice? 'Cause I've had that dinner.

Sheldon Cooper:
Well, I haven't. And while they say never meet your heroes, I just don't see how I could disappoint. Who would you choose?

Penny:
Robert Downey Jr.

Sheldon Cooper:
You... Oh! I didn't think of Iron Man. You know, maybe after myself and I have dinner, we can meet you two for dessert.
