During rehearsals McConigle's allergies act up. Lester has a plan to ruin Betty: a quiz show where she competes against Professor Answer, the man with the highest I.Q. ever measured, for $64,000. This will show the world how stupid Betty really is, or so the theory goes. Of course, the game is rigged. Meanwhile, Dr. Winky pays a visit and gives McConigle a potion that causes his allergies to go away. The quiz show takes place. Betty's partner is Mrs. Thissle, her grade school teacher, who proves to be a match for Professor Answer. Unfortunately, Mrs. Thissle thinks this is a rehearsal. When she realizes it's going out live, she panics. Lester thinks Professor Answer can't loose now, but the sound effect for a wrong answer drives the Professor crazy. McConigle, who's gotten high on his allergy medicine, stumbles on the stage and he and Betty end up winning the quiz show by a chance fluke answer.
