According to an explanatory survey, BUILDERS from Brum showcase the most underrated.
Bricks in England’s second largest city are the worst for keeping an eye on the passing public.
More than half, 54 percent, of manual workers in Birmingham admit they have shown more than they should.
Workers in London were next, followed by Newcastle, Bristol and Norwich.
Masons, builders, plumbers, carpenters, and plasterers are among those who give others a rush of vagrants.
Those in Manchester were least likely to expose a builder’s butt, the result of a belly button that caused the pants to slide down into the derriere.
The survey for Vauxhall Motors found that two-thirds no longer disclose themselves.
But while there are around 2.5 million shopkeepers and women in the UK, that means 825,000 still do.
Brickie Gregg Davies, 38, of St Albans, Herts, said: “Builder’s bum is a British institution and something we should not be ashamed of.
“It’s a sign of hard work – we’re too busy sewing our trousers and if anyone is bothered they need to take a good look in the mirror.
“There are times when I go to work and I come across a row of bricklayers bending over me while their punks are at the show, and it’s keeping me from my bacon bread, but you guys keep the job at hand.”
The contractors came to redo my garden but they got the wrong house – I’m not telling them, I want new decking
