If you don't have a head for heights, you may want to head to another story - here's one of a cat on a bike ride - but if you're still with us, here's two unicylists in Romania filmed riding around the top of a huge chimney, 256 metres above the ground.
Did we say riding? There's also one-wheeled bunny-hopping, some juggling of oranges, and hanging one-handed from a beam with a drop beneath of a distance that would take Usain Bolt 25 seconds or so to run ... but a little over 7 seconds for the average human to hit the ground if the worst happened.
The intrepid riders taking on the tower in Târgu Jiu, Romania are Flaviu Cernescu and Nikolai Ismail.
"Sick" is how one road.cc staffer described the video - more a comment on how they felt after watching it (well, till the halfway point, when they decided they'd seen enough) than on the riding itself.
