During the summer, Vicky uses the radio to promote her babysitting service and make kids work all day, but Timmy fights back as "Double T."

When Timmy is shouted at one too many times, he wishes that everyone would just be quiet for one day. Cosmo and Wanda grant this wish, and soon, Dimmsdale is eliminated of dialogue. However, a meteor is soon about to strike the town, and Timmy cannot undo the wish because no one can hear him, but he manages to wish the sound back by charading it.
