When Harry and Lloyd cover the car at the convenience store in gasoline, a Bell Atlantic payphone is in the background, with a blue and green logo. In 1986, the payphone would've had a New England Telephone logo. The company became Nynex in the early 1990s, and merged with Bell Atlantic in the late 1990s.
