2x17 - Maniac Mansion

Tina asks Fred if she can go on a ski trip, and he says yes. However, she'll have to watch Turner and Ike when everyone else goes on vacation. As soon as they leave, Ike calls all his friends and tries to have a party. She tells Turner to stop Ike, but he doesn't think he can. After Turner throws Ike across the room, he realizes his own strength. Since he has power over Tina and Ike, he makes them his slaves. To scare Turner and Ike into doing what they're told, Tina pretends that she's made herself super strong in the andromeda chamber. Ike and Turner then clean up the house and start obeying Tina. After realizing what a good job Tina did, Fred lets her go on the ski trip.
