Marshall: Married!
Barney: What is wrong with you? You're just looking. It's like fantasizing about other women. It's harmless. Wait. Don't tell me you don't fantasize about other women.
Marshall: I do! It's just not that easy.
Barney: False! I once fantasized about that silhouette chick you see on a truck's mudflaps. Took me less than a mile.
