If you want to see Kanye West smile, all you have to do is get him on "Celebrity Family Feud."

The rapper appeared on Sunday's episode of the Steve Harvey-hosted game show, joined by wife Kim Kardashian West along with three of West's cousins, and he pretty much had the best time ever. He was so smiley that viewers everywhere couldn't help but comment on it. Once the episode premiered, all kinds of tweets about West's love for "Celebrity Family Feud" piled up.

During the competition, West and his family faced off against Kardashian West's mother, Kris Jenner; her grandmother; her sisters Khloe Kardashian and Kendall Jenner; a cousin; and a close friend. They made it clear that they're all big fans of the show, but as the tweets below point out, it was West in particular who looked like he was in seventh heaven.

Even Kardashian West noted her husband's enthusiasm, tweeting that he had "a permanent smile on his face" during the show.

The rapper might just be the show's biggest fan.

"Celebrity Family Feud" airs Sundays at 8 p.m. ET/PT on ABC.
