The BBC has an article about a guy trying not to die of stupidity:

A unicyclist has been performing stunts on top of a chimney in Romania that is two hundred and fifty meters high, one of the tallest structures in the city of Targu Jiu.
Flaviu Cernescu (photo), who was not wearing a safety harness, filmed the stunt with a friend and posted it on his YouTube channel:
