A cheeky fighter tickled his opponent's armpits while competing in a bamboo boxing game above a canal.

Footage shows the pair, Job and Beer, grappling on the narrow pole over a pool of water for a novelty boxing match in Chonburi, Thailand.

Job sat balancing on the beam while the Beer hung below before the foe used his toes to prod both underarms.

Unable to hold on, the Beer slipped and dropped into the water, drawing laughter from spectators.

Spectator Off said: ‘It happened at Pattaya Floating Market. It was Job's final move. He unleashed his special attack, and it ensured he won.'

Bamboo boxing over a river is an entertaining activity often seen at festivals in Thailand, especially in rural areas. It is called 'Muay Talay' in the local language, which means 'sea boxing'.
