You would think people would know by now that it's not a good idea to start a fight with Arnold Schwarzenegger.
And yet one man on Saturday took a running start and dropkicked the 71-year-old former California governor at his annual Arnold Sports Classic in Johannesburg, South Africa.
Cell phone video posted on social media shows Schwarzenegger mingling with fans and filming someone jumping rope when an unidentified man runs up behind him, jumps in the air and kicks him the back.
The man was immediately wrestled to the ground and can be heard screaming, "Help me. I need a Lamborghini."
