He Should Have Worn Swim Shorts.

A man got a nasty surprise when he tried to get out of his deckchair and found his testicals had become stuck between two slats of wood.
Mario Visnjic had been swimming naked off Valalta beach in Croatia and his testicles had shrunk in the cool sea.
When he sat down they slipped through the slats and then, as he lay in the sun, expanded back to normal size.
He was freed after he called beach maintenance services on his mobile phone and they sent a member of staff to cut the deckchair in half.

So the next time you go swimming remember to wear your swim shorts.
