What did Reese throw in Humilithon?
In "Humilithon" (Season 4), Hal, Lois, Malcolm and Reese are driving to school. Apparently, the boys don't want to be seen at school with their parents, and the following conversation takes place:
Lois: Hal, look, hereís the parking lot.
Malcolm: You can let us out here.
Reese: Yeah Dad, hereís good.
Lois: Donít be silly, weíre all going to the same place. Hal, look, a space right up front, right next to the Cheerleaders.
Malcolm: (as he and Reese run away from Hal and Lois) Thanks for what you did back there.
Reese: Firecracker did all the work. Thatís the good thing about Cheerleaders, they stand peat easily.
Malcolm: Letís get inside before Mom and Dad see Ė (they see Mr Herkabe)
Now, could someone kindly explain to me what exactly Reese did that earned him Malcolm's gratitude?
