It's not easy being green - as one Brazilian man proved when he painted himself to look like the Incredible Hulk - and found the colour wouldn't wash off.
Pool attendant Paulo Henrique dos Santos, from Vila Cruzeiro, dressed up as the comic book hero for a running event, but got a nasty shock when the time came to remove the green paint.
After frantic scrubbing, the hapless chap realised he'd used a paint reserved for ballistic missiles and nuclear submarines.

According to Brazilian news site Extra.globo.com, Paulo had hoped to buy a brand of paint he'd used on a previous outing as the Hulk, but the shop he went to didn't have it.
Desperate to undo his inking, the would-be superhero spent Sunday and Monday having 'about 20 baths,' and was forced to sleep in a room lined with plastic bags.
He feared the industrial paint could actually give him lead poisoning, though he appears to have had no symptoms.

It was only after being scrubbed by a gang of friends and neighbours for 24 hours that Paulo finally removed the stubborn staining.
So was he left feeling blue? Amazingly, Paulo says he doesn't regret the incident.
