Ken is the head coach of the McKinley High football team who has a crush on Emma Pillsbury. They get engaged, but he ends up leaving Emma right before their wedding after realizing that she's in love with Will Schuester. This is probably for the best, considering Ken wanted Sisqo's "Thong Song" to be the theme for their wedding dance. Even worse? Ken has no toenails due to a raging case of athlete's foot (ew!).
