“Hit him, Lenny! You too, Carl!”

Man. Carl is beating the absolute hell outta Lenny. He just keeps punching! Why won’t anyone stop this?!

Mr. Burns starts a fire drill for the power plant, which the employees fail because they panic and take a long time to evacuate.

After everyone’s out and the drill is over, Burns scolds the employees, saying they need to improve their teamwork.

Carl says maybe Lenny does but he himself doesn’t, which upsets Lenny and they begin to fight.
