Wanting to get rich quick, Bobby begins selling bottles of hair tonic. But the tonic turns Greg's hair orange just days before his high-school graduation. In what happened to be the final episode of the series, series star Robert Reed got himself written out of the episode when he objected to the episode's plotline and writing and neither he nor the Schwartzes would budge.
