Big Bang Theory Quote
Sheldon: (learning Leonard has a girl over) This is very awkward.
Penny: Oh, come on. You know, Leonard's had girls over before, right?
Sheldon: Oh, yes. But there's usually planning, courtship, advance notice. You know, last time I was able to book a cruise to the Arctic to see a solar eclipse.
Penny: Wait, wait. You had to leave the state because your roommate was having sex?
Sheldon: I didn't *have* to, the dates just happened to coincide.
