Adam (Sean Giambrone) is about to go through a rite of passage on The Goldbergs.

It's Hell Week on Wednesday's Season 3 finale (8:30/7:30c, ABC), during which the incoming high school freshmen are hazed by the upperclassmen. Just when it looks like poor Adam might be the victim of a shower ambush at the hands of Barry (Troy Gentile), lil' bro finally turns the tables on big bro and decimates him.

Barry is just as surprised as anyone. But lbr, he's had it coming ever since the Adam bomb.

Check out the ass-kicking in the exclusive sneak peek above.

The Goldbergs airs Wednesdays at 8:30/7:30c on ABC.
