People rolling cheese down the street is something you probably haven't seen that many times before - if ever!
Well, that's unless you live in the English village of Stilton.
The annual Cheese Rolling World Championship happens there every year in May.
It seems the grate, if strange, tradition started when a local business owner wanted to come up with a new thing to draw visitors to the area.
Absolutely Brie-lliant... OK, sorry for bad jokes.
Check out the video to see some wheelie great cheese rolling athletes - that's if they don't just whizz pasteurise!
