Weird Science 4x23

Master Chett

After receiving too many memory-wipes from Lisa, Chett develops a brain callous that no longer allows his memory to be erased. This allows Chett to know about Lisa and the fact that she’s a magical genie. Of course Chett wants to do harm instead of good. He immediately tries to lie, bully, and buy his way into getting his very own genie from the guys. Unfortunately, instead of a genie, he gets a nice ride to the insane asylum.
