Stephanie has the chicken pox, and it spreads to Jesse and Joey. As part of his TV sportscasting job, Danny is scheduled to be on the bench at a Golden State Warriors basketball game in 40 minutes, and with D.J. going to her first slumber party, Danny is having a hard time finding a babysitter for Michelle, who has never had the chicken pox. With only 40 minutes to find a babysitter, Danny becomes frantic, then he begins to believe that he’ll miss his assignment at the basketball game…until someone makes a surprise sacrifice so Danny can go to the game — D.J. has willingly decided to stay home and not go to the slumber party, so she can take care of Michelle so Michelle won’t have to be near Jesse and Joey while they still have the chicken pox. Chicken pox also means that Stephanie will have to miss an appearance at school by a real ballerina, something Stephanie never wanted to miss.
