A man has a botfly maggot surgically removed from his head a month after it burrowed into his scalp in this gruesome clip.
The man, called Simon, uploaded a YouTube clip showing the moment the larvae is pulled from his skull using tweezers.
He apparently brought the "souvenir" home from a trip to Panama, and had hosted the parasite for a month.
The stomach-churning video starts with a view of the top of Simon's head. The maggot can be seen moving around underneath his skin.
The fly: The maggot is gradually pulled from Simon's head
A friend, who is filming the extraction, says: "This is seriously insane."
He asks the woman who is performing the procedure why she can't just pull the botfly out with tweezers.
Month old: The maggot had been living in Simon's head ever since burrowing into the scalp in Panama
She replies: "It has to come out a little bit so I can grab it.
"I think this isn't far enough. I'm worried that I will rip it apart which at that size is likely to happen."
It then poos out of the top of Simon's head, to the disgust of everyone.
Cutting to black, the words "ages later" appear on the screen to the strains of Vivaldi's four seasons.
We then see the botfly pulled out in one piece - leaving a large hole in Simon's scalp.
"Oh my God it's huge!" exclaims his friend, before he and the woman start laughing.
Writing beneath the video, Simon, who uses the Youtube name Mighty Jungle , said:
"Yeah its a little bit disgusting but I added some Vivaldi so its fine."
