When Beverly gives Adam a "best son" trophy, Barry brings to her attention that she always favors Adam. Appalled, Beverly decides to ignore Adam (much to his delight) and smother Barry (much to his dislike), but it backfires. Meanwhile, Erica starts dating a boy who gets her to love the band Rush as much as he does and whom Murray doesn't approve of.

Barry and Erica forget to get Beverly a Mother's Day gift and make last minute "Mom Coupons" instead. Beverly is understandably hurt, and decides to get revenge by cashing in every coupon they have made. Meanwhile, Adam tries to get Murray to let him go to space camp and accuses him of being as dream crushing as Pop-Pop.
