Sheldon and Penny are two characters on The Big Bang Theory. They have a very snarky relationship, and a lot of people want them to end up together. But she's Leonard's (Sheldon's roommate) woobie, so it probably will never happen.

And Sheldon's pretty asexual. He invited a girl to stay at his apartment, in his room, in his bed. When she got there, he showed her his room... and went to sleep on the couch. :D

Sheldon and Penny are from The Big Bang Theory. :D
