David and his date, Terry are at the malt shop with Rick and his date, Jane. They are all out on their first date and Rick wants to take Jane bowling. Jane accepts and Dave asks Terry if she would like to make it a foursome. She declines because she has too much studying to do. Jane asks Dave if he would like to come along with them. Dave declines because he doesn't think Rick would appreciate it.
The boys come home and tell their parents about the girls they have just met. Rick gets a phone call from Jane who can't go bowling with him since she has to babysit her little brother. Rick thinks Dave could babysit for them so they can still go on their date. Rick asks David to babysit and eventually convinces him to accept the job.
When David arrives to babysit her little brother, Bill, he asks Dave why she didn't go out with him. Bill tells her about how Jane talked about him all at dinner and that she likes Dave not Rick. David takes this to heart and soon finds himself bumping into Jane all over campus. He also discovers that he is falling for his brother's girl.
A nice change of pace to have a girl fall for Dave over Rick. It was a great idea and the episode was truly a delight to watch.
