Jamie is starting to act exactly like the other 4 boys have, very rambunctiously. However, after he knocks over a bookcase which nearly crushes Lois, she is just about ready to give up on him, but instead she has Francis come over, who starts to remember his life in the all-white apartment, where he wrecked the place, and Lois was trying to be the good parent and coddling him. Eventually, though, after Francis nearly lights himself on fire, Lois shows EXACTLY what fire does, and Francis finally buckles down. Outside of the flashback, Francis is in tears over the whole thing, and Lois finally has some order again. However, it is revealed that Reese has been giving Jamie caffinated drinks.
Meanwhile, Reese, Malcolm, and Dewey find an old diving board and take it home to try and figure out what to do with it. Reese is going crazy trying to figure out what he wants to do, so Malcolm and Dewey come up with a crazy "Jackass" style stunt. But when Reese goes to climb the board, the board comes apart and falls on top of him, and the fireworks on his head for the stunt then go off.
