'The Blue Light Disco Sketch' is a much loved sketch from Episode 6. It features Greg as Mr. Duncan, Eddo as Ms. Dunch, and Ben as Mr. Shnreb (the asexual maths teacher). The teachers investigate poop on the lid of a toilet as well as the fingering of Jessica Harris by Timothy Sutton. The sketch is notable for the being the first sketch ended with a blast off.
The Teachers' most recent appearance is Episode 102, a live episode, where Mr. Shnreb finds soiled underpants in a bin. This sketch also ends in a blast off.
