That is either a very small monkey or a very large ponytail

This dude got arrested because he tried to smuggle a monkey on an airplane in his ponytail:

A passenger who originally departed from Lima, Peru, and connected in Fort Lauderdale had been hiding the small monkey in his ponytail, under his hat, according to Spirit Airlines spokeswoman Alison Russell.

During the flight, the monkey crawled out of its hiding spot, forcing the owner to hold it in his hands, where the unexpected visitor was soon spotted by fellow passengers and crew members, Russell said.

Awesome. I mean every time I think the human species cannot become more ridiculous, they just try so much harder. He cannot have possibly believed that was going to work.

I guess you don't have much choice though. Can you even bring a monkey into this country? Even if he put it in a dog carrier or something, I doubt customs would let you keep it.
