The glee club led by Mr. Gooster and the Gheerios led by Sue are arguing about two sounds that the letter 'g' makes, before they launch into a song to the tune of 'Don't Stop Believin' '.
"Sesame Street" debuts a new spoof of "Glee" just in time for the season 3 premiere of the FOX musical series. It opens with Mr. Gooster, which has a prominent cleft chin like Matthew Morrison's Mr. Schue, telling his students to find a song about the letter "g", prompting a muppet which mimics Rachel's hair-flipping gesture to show off her vocal.
All the G club members then sing the song together before gym teacher Sue interrupts them and tells her Gheerios girls, one of which has Quinn's breathy slow voice, to sing about the letter "g". The two groups then argue about the two different sounds that the letter "g" makes.
The letter "g" shows up to stop the argument and tells them that it makes both "guh" and "juh" sounds. They then perform a song with more "g" letters to the tune of Journey's "Don't Stop Believin' ". The "g" letter says it is "grand", but Sue calls it "gruesome."
