In case you need a reason to not get too close to an alligator, let this video be that reason.
While on vacation in Florida, this guy was on his boat making his way through a marsh when he came upon a gator.  He pulled out his phone and fired up Facebook Live, just in time to catch the gator JUMP INTO THE BOAT.  Obviously, everyone on the boat lost their f***ing minds while the gator thrashed around for a bit.  The prehistoric beast eventually made its way back into the water, but not after a bit of a struggle.

So take our word for it, folks.  Stay away from gators!
