Seems to be a Welsh activity.
Bog Snorkelling Game
Every Bank Holiday August, the town of Llanwrtyd Wells hosts one of the country's strangest contests - the Bog Snorkelling Championship. If you don't fancy all that thrashing around in the mud, take our online Bog Snorkelling challenge...
The game's not as easy as you think - you're not allowed to use normal swimming strokes! Instead you have to keep wiggling, splashing and flaying around (by alternately hitting the keys on the keyboard that randomly appear on the screen) until you start moving. Oh and don't forget to keep breathing (using the mouse to drag the bubbles onto your snorkel).
Hmmmm. Think Edward will want to play? Too bad we can't take Bergamasco's bog snorkeling. Now that would be a picture!
