But that's really not where the action is. Not even close. Sean Penn, in fact, just might have set off one humdinger of a Celebrity Spat as it also involves Matt Stone & Trey Parker, the guys who do South Park and the makers of the upcoming Team America, a movie we are almost giddy about the thought of seeing (puppet sex!). We’re not talking about some lightweight Lindsey Lohan vs. Tara Reid battle here, we’re talking a bare-knuckles, knock-down, drag out spitball fight between two heavyweights. We're talking Jeff Spiccoli vs. Eric Cartman. Beef Cake! Beef Cake!
