This is in the episode where Dante and Randal are being sued after Jay slips and falls in the Quick Mart. Early in the show Dante and Randal are cleaning up the store and Randal throws his orange soda into the plastic garbage bag that Dante is holding. The very next shot, however, shows that even though the soda can missed the bag and fell on the floor, Randal is holding another can which apparently appeared out of nowhere.
