Given bad advice by his older brother, Davey, Dobie convinces a girl that he is having an affair with his teacher.

Thalia wants Dobie to become a popular singer, but he hasn't the voice for it--that is, until he gets his tonsils out. Now he can croon and make girls swoon--but with all those girls after him, will he forget Thalia? Also, this is the only episode featuring Jerome instead of Maynard.
