Following a gig, Paulie and David spend the night with some groupies. The following morning they oversleep and realize they might miss one of there most important shows, a kid's party for a record executive, that could give them a deal.

The guys show up to a kids' party in Long Island and learn it's been double-booked. No problem, except for the fact the other band is Kidtastic! - their nemesis in the kiddie world. Joey seeks relief from those goofy bastards, Paulie seeks relief from a persistent rash, and David seeks relief from a persistent female admirer - Kitty Braunstein. In the end, all 3 of them get their "heads" examined.

While playing at a bris, the Z Brothers meet John Popper and gives him their CD. After listening to their music and with a little help from a friend, John Popper offers them a record deal.

John Popper shows the guys how sweet life could be as a full-time kids' band when he lands them a party for Gilbert Gottfried's son for $10,000. The band gets a taste of the rocker good life, Dina gets a taste of Harry's crazy side, and the insatiable Kitty gets yet another taste of David.

Haunted and confused by his feelings for Paulie, Neil terminates ZO2's regular gig at Southpaw. With the future of the rock band in question, Dina lands them a gig at Manhattan's Cutting Room. Only it's jazz night, and the crowd doesn't dig their sound. The guys somehow dodge an all-out race war and win over the audience, Joan Rivers, and a tearful Neil in the process.
