YouTube pranksters have an obsession with the fast food drive-thru.

For his latest prank, Jack Vale teamed up with Greg Davis Jr to pull a fast one on the employees working the drive-thru. After taking one of their orders, Jack or Greg would ask for a bottle of water, giving them just enough time to jump in the backseat and swap positions without being noticed.

By the time the worker returned, they were lost in utter confusion.
