David Rosenburg

David Rosenburg was a boy at the Lock-In in The Ugly Truth. After Mr. Palmero suggested that the boys go behind the auditorium curtain to pass gas, they take turns going there and making obnoxious noises; David Rosenburg gets a tuba from the music room and blows it behind the curtain. After that, the heat in the auditorium went off.
