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.
Question: When Barry refers to the stop sign in his room he says "The stop sign where she wanted to go left and I wanted to go right, so I got nervous, went straight." As he was talking about Lainey, soon after Murray says "Well, let's get in the damn car. And bring the stop sign. We got to put it back. It's a serious crime." Is Barry's quote some kind of sexual innuendo, or is it that he actually, accidentally drove into it because of Lainey?
