Why in hell?

It makes no sense that these guys would do this.

I’ve sat here and tried to think of reasons why these fellas would do this picture, and I’m stumped. They all lost a bet? Way too much alcohol? Sounded like a good idea at the time? Brain damage? Wives talked them into is via some evil scheme to collectively bring their men down? Some weirdo offered them a LOT of money? No, that can’t be it, there isn’t that much money. So? And the little dude on the right, what the eff are you doing anyway, pal? Just wholly bizarre.
