Malcolm coaches Dewey on how to do poorly on an IQ test so he will not end up in the Krelboyne class; the trick works too well and Dewey is sent to the emotionally disturbed "Busey" class instead. Meanwhile, Reese tries to figure out what type of genius he is, and Hal and Craig enter a Dance Dance Revolution-style contest.
