Penny: Leonard, look, if you want to meet my friends, that would be great. I just, you know, I didn't want you to be bored.
Leonard: I wouldn't be bored. Why would I be bored?
Penny: Well, 'cause they're not genius scientists.
Leonard: Penny, I like all sorts of people. In fact, some of my best friends aren't geniuses.
Penny: Like who?
Leonard: Okay, some of my Facebook friends aren't geniuses.
