Goldbergs: Watch Wendi McLendon-Covey's 2016 Emmy Reel Now

Adam’s self-consciousness about his pubescent body on The Goldbergs may not feel like a laughing matter to the boy, but star Wendi McLendon-Covey turns his misfortune into comedy gold in tonight’s episode (ABC, 8:30/7:30c).

As you’ll see in TVLine’s exclusive video, when Beverly discovers that her son is failing P.E., she thinks she knows why he doesn’t love swimming anymore.

“It’s your bathing suit. You’re growing fast and it’s pinching your little coin purse,” she declares, showing off his new trunks — excuse me, “jams.” (If there’s any justice in the world, the  exchange will make McLendon-Covey an Emmy contender next year.)

But it’s not Adam’s “little marbles” or “yam bag” (as Murray dubs it) that are the problem.
