Like you do.
I think that the dude in question may have mental issues, as he apparently was screaming “I need a Lamborghini” as they dragged him off. So I’m going to try to not make fun of him in particular — but, damn. Say what you like about Arnold Schwarzenegger (I have a list of several things that I could say about Arnold Schwarzenegger); the man can absorb a blow*. I really don’t think that was the expected outcome of the attacker.
*I grant that Arnold moved. That’s just physics. Soaking the damage like that? Dude’s in good shape**.
**I also grant that Arnold may be sitting in his hotel room right now with several bags of ice on his back. If so, I shall keep his secret.
