A man walking his dog bumps into a man.

The man, "You should look where you're going next time."

Three minutes later the man with his dog walks into him again.

"Seriously," shouts the angry recipient, "Stop walking into me."

A few minutes pass again, the man and his dog bump into the man for a third time, this time knocking him to the ground.

The man screams, "Oh my god. Stop this! Take off your sunglasses, it might help you see."
