Hmm suggestion... Enjoying the Foreplay.
Do you have any?

Yep!

Penny (to Sheldon): You reading, me reading, we're like an old married couple!

Sheldon (to Penny): I'm the guy..It would explain so much. You’re constant presence in my apartment, that baffling dalliance with Leonard just to be near me. The way you call me sweetie all the time.

Sheldon (to Penny): I came to ask if you would like to go on a date with me.

I like the first one and second one. But the second one is kinda long to have as a motto.

P: Sheldon has to get me into bed...
S: Yes. The charm of your drug addicted candor knows no bounds.

Nice one _naiza!
Also this: Sheldon (to Penny): A date, you and me. Dining, dancing, perhaps you'd like to take in a prize fight.

I think that the "old married couple" is the best! :3
