Two guys standing on a sidewalk notice a
man being robbed. A stranger runs up, punches the robber in the back of the head and proceeds to give him a hellacious beatdown. Afterwords,
the man thanks the stranger and the stranger tells him simply, "Don't mention it." and carries on about his day.
Guy 1: "
Man that was crazy!"
Guy 2: "That dude must have been a Deitz!"
