Happy Slapsgiving!

When How I Met Your Mother is funny, it's HILARIOUS. One of the funniest running gags on the show is called The Slap Bet - Marshall (Jason Segel) and Barney (Neil Patrick Harris) have a bet, which Barney loses...which gets paid out in the form of five slaps to the face, whenever Marshall chooses.

This was one of the planks of this week's show, where Marshall chose to tell Barney that he'd be slapping him on Thanksgiving - aka, Slapsgiving.

Totally lived up to the hype, and Marshall's glee of "I wrote a song about it to celebrate!" was also great.

What is this feeling that's put you in your place?

The hot red burning on the side of your face?

You feel the blood rush to your cheek.

Tears start to fill your eyes, and your lips are trembling and you can't speak,

And you're trying, you're trying not to cry...

You just got slapped!
