The Simpsons S28 E06 There Will Be Buds

"Just a product of society that's lost its good manners."

Homer gets roped into coaching the kids' lacrosse team with Milhouse's dad, Kirk, who is in desperate need of a friend. When Kirk gets too clingy, Homer vents about how much of a loser he is. Kirk overhears his rant and disappears, right when the team needs him most: the championship game.
