Big Bang Theory Quote
Sheldon: I must say, Leonard, ever since you've been having regular intercourse, your mind has lost its keen edge. You should reflect on that.
Leonard: Excuse me, but Einstein had a very busy sex life.
Sheldon: Yes, and he never unified gravity with the other forces. If he hadn't been such a hound dog, we'd all have time machines.
