Must have been trying to pick his nose.
Stupid people will do stupid things.
When I worked as a gastroenterology nurse, we had a guy who came in the ER with a fishing hook stuck in his rectum. He had eaten fried chicken the day before...chewed and swallowed the chicken bones and all. Then some splinters of the bone got stuck in the rectum. So he thought that it was a good idea to use a fishing hook to grab the bones and pull them out. Needless to say, it was a “$hit-show” that required surgery.
