[after slapping Barney, Marshall plays the piano, performing a song]

Marshall Eriksen:
[singing] What is this feeling, that's put you in your place? A hot red burnin' on the side of your face. You feel the blood rush to your cheek, the tears that fill your eyes. And your lips are trembling, but you can't speak. You're tryin', oh, you're tryin' not to cry. You just got slapped, oh, across the face, my friend. You just got slapped, yes, that really just happened. Everybody saw it. Then everybody laughed and clapped. It was awesome. Wait, you just got... slapped. [stops singing and playing the piano] Happy Slapsgiving, everybody.
