A young lady sitting on a bench with her dog asks passersby if they would watch her dog for a minute while she goes to the porta-potty.
What these unsuspecting victims don't realize is that the porta-potty has a back door. After she has slipped out the back door a couple of construction guys come along and remove the porta potty.
The person sitting on the bench watching the dog is left wondering if where she went and what to do with the dog. But it's all good fun and it seems like the dog is even in on the joke
