Get a bad sunburn or tan is one thing, but getting it on top of your head for the entire world to see is another. And there's a name for this terrible phenomenon. It's known as a hat tan.

In this amazing gallery, you'll see guys with some of the worst hat tans probably in history. Though we have to wonder what hat tans were like way back in the day when more people were farmers and wore things like suspenders and top hats. We're guessing they kind of look more dignified than the guys with hat tans in these photos.

From professional golfers to the frat dude next door, it seems like nobody is immune to the dreaded hat tan. The best ones however have to be the mug shots. I mean, it's bad enough that you got arrest and are even in a mug shot, but then to have a hat tan on top of it? That must be the worst!

What I don't quite understand, however, is how these guys managed to even get these hat tans. How did the sun manage to tan (or lets say burn) underneath a bill. Isn't that actually the point of a hat? To protect your head and face from the sun? It's all very, very, weird. But also enjoyable.
