Step Brothers 

The best god dam motherfucking kick ass boob jiggling, unbelievably fucking funny movie staring Will Ferrel and John C. Riley. These 2 fuckheads are the best pair of comedians to put into a fucking movie. I almost pissed myself watching this fucking hilarious shit. If they made a squeal, every fucking smart person from Toledo, Ohio, HSAT in the downtown would go see this fucking amazing funny ass shit.

Step Brothers

Will: John you awake?
John: Yea
Will: Ima punch you right in the fucking face
