The set for Jerry's (Jerry Seinfeld) apartment and the studio audience seating had to be removed to make room for the parking garage set. Mirrors and different camera angles were used to create the illusion of a multi-level garage.
Throughout this episode Kramer (Michael Richards) is seen carrying around a box with a new air conditioner in it. At Michael Richards' insistence, the prop department placed an actual air conditioner in the box. Richards wanted to make his struggle with the box seem genuine.
When Kramer (Michael Richards) struggles to put the box with his air conditioner into the trunk, resulting in him simply slamming the box into the trunk hard, Michael Richards injured himself. He banged his lip on the box's corner, cutting it open. Thus, sending the other cast members into genuine laughter. Richards himself managed to stay in character, as he looked at Julia Louis-Dreyfus and said "I really hurt myself, Elaine." While, the line and reactions from the cast is not seen in the final episode, it can be seen on both the third season DVD's "Inside Look" and in The Seinfeld Story (2004) (TV).
Larry Charles, one of the main writers of the show, made a cameo appearance as a man who ignored Elaine (Julia Louis-Dreyfus) when she is asking around for help.
