In this episode, D. J. got a sudden taste for acting after a successful part in a play. So without thinking, Jesse suggested she try to get an acting part in a commercial. Of course, Danny was grateful...not...but he found her a part and gave her permission to go audition.
D. J.'s audition went well. The woman conducting the auditions was all set to hire her, but Stephanie ended up with the part purely by accident! D.J., of course, is very, very unhappy and chooses to ignore her sister. Danny warns Joey and Jesse before he goes to work that an explosion is about to happen, and it does. They have to deal with the consequences.
A sub-plot in this episode: Joey gets some test results back from the doctor and decides to go on a health food diet and give up ALL junk food. The results is a lesson for us all.
There's nothing earth-shattering or new in this episode, but we do see the sisters fighting. This is really the first time you see Jesse and Joey disciplining the girls.
