Plot summary
While Matthew plans a stellar bachelor party for Richard, New Christine insists she was content with her office bachelorette which consisted of a coffee break at the downstairs shop. Barb convinces Christine that they should take New Christine to Vegas for a proper bachelorette where she tries tequila (and many other things) for the first time. Richard's brother (guest star Charles Esten ) comes in for his bachelor party and is totally insulted that Richard has asked Matthew to be his best man.
