Jen and Lauren are organizing a customer's clothes closet. Jen throws a pair of shoes onto a shelf and the shoes land askew. When Jen's cell phone rings and she answers the call, the shoes are neatly side by side. When she finishes the call and kneels down, the shoes are once again askew. When she stands up, the shoes are again side by side.
When Jeff and Lauren are at the store buying tampons and an adult magazine there is a cameo by 10 Second Tom - a character from 50 First Dates (another movie Sandler and Barrymore made together).
