A 100% True Ghost Story - S7-E6
Trivia: Barry plans a Rocky Horror Picture Show themed party. The professor he speaks to about his failed test is named Professor Majors, and is played by Barry Bostwick. Bostwick played Brad Majors - A Hero, in The Rocky Horror Picture Show. The joke continues with a clumsy girl knocking things over and Bostwick ripping off his glasses saying "Dammit, Janet!" just as he did in the film.
