Bentley Gregg goes on a detective mission to find out the identity of the person in Kelly's class who is getting married. He assumes it's a student, but what Kelly won't tell him is that it's actually her teacher.
Bentley suffers the trials and tribulations of helping a small jazz combo from Kelly's high school rehearse for a Battle Of The Bands contest. Their new pushy young sax player becomes the bane of everyone's existence - especially Bentley's.
After Uncle Bentley says absolutely not to Kelly's request to dye her hair blonde, she makes a bet with him that if there's evidence that his redheaded girlfriend dyes her hair, then Kelly can dye hers, too.
Against Mr. Gregg's advice, Peter, with the help of Kelly, Ginger, and Howard, goes into business making and selling homemade fortune cookies. The bureaucratic red tape that Peter encounters takes up so much of Mr. Gregg's time that it jeopardizes a million-dollar deal at his law office.
16-year-old Kelly gets in over her head after lying about her age to a 22-year-old college man because she wants to date him. She tells him that she's 19, and surprisingly, she gets Uncle Bentley to back up her lie.
