Cartman's "Big Plan" for Kyle

After destroying Hippie Fest 2005, Cartman approaches Kyle with a knife who begs him not to kill him since they're not hippies anymore. Cartman tells Kyle not to worry since he has "bigger plans" for Kyle...which involves him playing with the Tonka radio-controlled play bulldozer while not letting Kyle have a turn with it.
