How I Met Your Mother Season 3 Episode 5

Marshall: I'm not gonna cheat on my girlfriend.
Barney: Yes, you are, with the hottie that just walked in. Look at her. (about Lily) How much hotter is she than your girlfriend?
Marshall: There's no comparison. What do you think, Ted, should I go for it?
Ted: Don't do it, man, think about Lily.
Marshall: You know what, I don't care, I've been with the same woman for too long. I need me some strange.
Barney: Yes, yes! Okay, pep talk! You can do this, but to be more accurate, you probably can't. You're way out of practice and she's way too hot for you. So, remember, it's not about scoring. It's about believing you can do it, even though you probably can't. Go get 'em, tiger! Poor guy's going to crash and burn. (Marshall and Lily kiss) That man is a GOD!
