Quote from Marshall in The Naked Truth
Lily: Wait a minute. You're going to date two girls at once? Don't you think you should just choose one before it gets serious? Ted: Define serious. Lily: Well, that's complicated. I guess you have to weigh expectations, emotional investments... Marshall: Third base. Seriously, third base. Ted: So I can go to second base with both of these girls, no problem? Marshall: Oh, honk away, my friend. Yeah, honk away.
