While his boss keeps Dorothy Bovine captive, Bart makes several attempts at blowing up her safe. The end result of his buffoonery results in the safe dropping on Moo-ing's head.
The sketch ends, serial style, when Bart engages in a fist fight with Lash Holstein. In the next "episode", the two continue to brawl, destroying Dorothy's house. Bart is eventually defeated off-screen as Lash ultimately finds himself breaking into Moo-ing's spacecraft to save Dorothy.
