Full disclosure - we don't even know if this guy is a real gladiator. We mean, he definitely looks like one and he is definitely wearing gladiator-style armor. But we're not quite sure what the deal is with the dead bear on top of his head. This is way more over the top than a bearskin hat - it's an actual full bear perched up there! Animal rights activists would certainly have something to say about this if it happened in modern times.
Luckily for us, we don't have to worry about ever encountering men wearing dead animals as hats. Or the activists that would surely be making noise about it. Let's be grateful for that and start hunting for the three differences hidden in these pictures instead. A little hint: they're not in the bear hat.
