After a falling-out with Rutherford, the guys are recruited by Roxie's rival event planner - and former assistant - Emily Corgy (guest star Erinn Hayes) to play an "End of the World" party. The guys don't feel good about the career move after learning Tommy and Emily have started dating. Worlds collide when they learn the event they're scheduled to play has been double-booked with another "End of the World" party thrown by Rutherford. Even worse, it's headlined by Mother of the Bride's rival - the Def Leppard tribute band Armageddon It (fronted by guest star Ken Marino). It's a recipe for disaster.
