This weekend saw the annual Bog Snorkelling Championship in Northern Ireland, where this competitor was trying to keep her head above water.
Do you think they'll stay this clean for long? Competitors had to swim through 120 yards of muddy water using a mask, snorkel and flippers.
This snorkeler is the centre of attention as the crowd snap away. The event took place on International Bog Day, to raise awareness of how important bogs are to Northern Ireland.
Sorry, but it's a long way to the finish line!
Cannonball! What can be better after swimming in a bog than a dunk in the bog Jacuzzi?
Now that's a much needed shower. This snorkeler gets a well deserved hosing down to clean himself up.
Out of the bog and into the...bog. These two boys can't get enough as they jump into the bog Jacuzzi.
This lady is asking for a mouthful of mud as she laughs, covered in mud.
Turn around! A confused snorkeler seems to be swimming away from the finish line.
