The producers of How I Met Your Mother are really pulling out all the stops for the show’s ninth and final season. In last night’s episode, Marshall and Barney’s long-running Slap Bet received its swan song, sung by none other than the Ambassadors of ’90s Sentimentality, Boyz II Men. The moment was surprisingly poignant. LOL, JK — it was just a wonderful montage of slapping.
