Black puddings are thrown at Yorkshire puddings on a ledge
Competitors from across the world have gathered at a pub in Greater Manchester for the World Black Pudding Throwing Championship.
Thousands are watching entrants from as far afield as Hong Kong, Africa and Sweden compete at the Royal Oak in the village of Ramsbottom, Bury.
The aim is to knock Yorkshire puddings off a 20ft ledge by throwing black puddings at them.
The contest is supposed to represent the Lancashire/Yorkshire rivalry.
Organiser Elaine Singleton says you need real ability to take part.
"It is skilful for a start. You can't throw overarm - you've got to throw underarm and it's got to be precise otherwise you won't hit any puddings.
"You try lobbing a pudding underhand 20ft up - you've got to have some weight behind you to do that!"

She added that the unusual competition was attracting as many participants as ever.
"Plenty want to do it. I get phone calls from all over the world to come here."
The popular competition was saved in 2003 after the previous venue closed.
Black pudding is traditionally made of cooked pig blood, fat and rusk, encased in a length of intestine.
The contest dates back to the 1850s and is believed to be a revival of the Lancashire-Yorkshire rivalry.
Historically Bury, now part of Greater Manchester, was in Lancashire.
