Danny is scheduled to do the 10pm sports at the TV station, Joey is scheduled to perform his comedy routine at the Laugh Machine at 10pm, and Jesse is scheduled to hold rehearsals with his band, Jesse and the Rippers, at 10pm, but one of the guys must sacrifice what he is scheduled to do and stay home with the girls. Danny and Joey choose Jesse to make that sacrifice, but Jesse finds a way to be with the Rippers anyway -- he invites the band over to the house for rehearsals in the living room, and of course D.J. and Stephanie don't want to miss it. That's why Danny is not delighted by what he sees when he gets home. Not only are Stephanie and Michelle still up, but their hair has also been colored purple.
