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?
