Dean works at Shenaniganz, a restaurant similar to Bennigans. He deals with his problems of the future and a possible promotion while he works through the day with his ridiculous coworkers.
There is a video online of Luis Guzmán having a fight with director Rob McKittrick after which Guzmán storms out and the rest of the cast is left in awkward silence. During the filming of the scene where Calvin imagines his co-workers cheering him on at the urinal, Guzmán replaced a line from the script in favor of his own line, which started a huge commotion. Unbeknownst to the rest of the cast, this was an elaborate April Fool's prank concocted by McKittrick and Guzmán.
