Bot flies are nasty little creatures. A mosquito or some other insect deposits little eggs in a host’s flesh, where the larvae grows … and grows … and grows.
Like this guy in this video. According to the Youtube description, he’s in the Amazon jungle and has to have a bot fly ripped from his scalp. And it took three days. The fly was so stubborn that he had to have some hair shaved away, before tweezers pulled the fly out.
All the while, he was in pain.
Yes, he was laughing, but it’s the laugh that someone makes because the only other alternative is crying.
And, he would have been forgiven for crying.
