Break me up before you go-go
When Zack and Slater fail to see eye to eye with their women about the merits of the ballet and Kelly's right to have a sugar daddy, it's trouble in paradise.

So Zack and Slater hastily get their girls back, by apologizing and acting like a flaming homosexual, respectively.
