Some things, you just shouldn’t do.

And messing with a near 20-foot long anaconda is one of them.

A group of fisherman spotted the anaconda and began filming themselves pulling the huge snake from the Santa Maria river in Brazil’s southwest.

The giant yellow reptile, with what looks like a swollen belly from a massive snack from earlier, is seen moving away from the tiny boat.

The fishermen can be seen grabbing the tail as the anaconda thrashes around trying to get away.

The jaw-dropping video is sure to give you nightmares
