Quote from Barney in The Ashtray
Ted: [on the phone] Uh, Captain, can... can I put you on hold? The Captain: Affirmative. Ted: He wants Robin's number. Should I give it to him? Barney: Is he trying to hook up with my fiance? No, uh-uh. The only way that's happening is if I get to hook up with someone, too. Wait a second... No. Unless... Absolutely not. However... Forget it. On the other hand... Ixnay! [slaps himself]
