The reaction on Twitter: #HowIMetYourRacism.
Monday's episode of "How I Met Your Mother" on CBS continued an ongoing joke about a slap bet between Marshall and Barney. In order to win the bet, and give the best slap to Barney, Marshall explains he learned the "Slap of a Million Exploding Suns" by seeking wisdom from three great masters.
It turned out these supposed wise ones were played by Marshall's friends — Colbie Smulders, Josh Radnor and Alyson Hannigan — in yellowface. People went to Twitter with #HowIMetYourRacism to takedown the episode.
