I was in the audience of a beard of bees contest a few weeks ago. It was the craziest thing I've ever seen.
There were two contestants, both of whom were professional beekeeper. They each hung the queen bee on their head and let the bees swarm them. Whoever got the most bees and could keep them on their body the longest won the contest.
The contestants didn't seem scared, the audience was more scared than they were. There were a lot of bees, several hundreds for sure.
