Harry Gilbertson was a kindergartener who participated the talent contest in Rodrick Rules. His performance consisted of riding around a stereo playing "Yankee Doodle Dandy" in figure eights on roller skates, and had to participate at the same time as Rodrick's band. He got a trophy for best musical act, upsetting Rodrick because that was the award he was least trying to get other then the grand prize. He was played by Spencer Drever in the film.
