When the main character walks into the convenience store where the store employee is the same man who was driving the boat car earlier in the film, the employee is wearing a uniform with a "Circle A" logo, the same as the logo for the Circle A convenience store where the main characters in SubUrbia spent most of their time.
Nicky Katt, who plays Tim in SubUrbia, makes a cameo as a clerk at Circle A convenience store. Circle A is also the name convenience store in SubUrbia that Tim and his friends hang out at.
