In an act that defies all logic, a man puts fire ants in his crotch and appears surprised when that's unpleasant

You know the old saying, "Liar liar, pants on fire"? Well, this Thai man found out that you don't have to be a liar to stick fire ants down your pants and have them be on fire. Why someone would willingly do this themselves, I have no clue. I'm still not sure what's worse, that this guy actually did this or that his friends decided it was a good idea to help him out.
