Yes, the holidays are over.
But How I Met Your Mother Season 9 Episode 14 made it clear that Marshall had one final gift to give Barney: the ultimate slap.
We flashed back a number of years on the fun installment, as Marshall time time told a crazy story about how he met with three masters of slap. Our favorite? Probably Ted as The Calligrapher. Ridiculous, awesome stuff.
Also awesome? The way Barney tried to appeal to Robin... but come on. She knew she could not get in the way of this inevitability.
So, with 17 hours to go until the wedding, how did things wrap up?
