Sideshow Mel, Moe and others in “The Cartridge Family”

[Lenny punches Principal Skinner in the stomach, knocking him into the aisle stairway. He collides with Barney's beer tray, spilling it. Barney, enraged, runs headfirst into the increasingly large number of people fighting on the stairs, knocking and bowling them over. Meanwhile, a group of Scottish men watching the game stare bored at nothing in particular].

[The men, rolling up their sleeves, start to pound anyone who comes near them. It's not long before the entire stadium is embroiled in a violent riot, from people getting tackled to Groundskeeper Willie's soccer hooligan friends hitting people with pipes to two East Asian guys in karate robes kicking each other in the face to Nelson sitting on Milhouse and pulling his leg back as Milhouse screams and cries. The Simpsons stand next to their seats.]
