Ah, that’s less likely to happen, but could have been a lucky hit. Musk looks like a guy who bruises easily.

Probably shouldn’t have given his kid those brass knuckles for their birthday, though.

I can’t believe I’m defending Elon Musk, but a 5 year old can easily give you a black eye. Just lifting them and them accidentally headbutting you can be enough. Doesn’t happen nearly as often as accidentally getting kicked in the nuts, but still believable.
