Mums in Italy were furious after discovering that the school bus their children were travelling on was carrying an advert for a sex shop.
The ad for local store Erotic Dreams was approved by the bus owner without any kind of warning to parents or pupils, despite the shop selling a plethora of products unsuitable for children.
'Our children are old enough to be able to read this advert and come home asking what it is all about,' said one mum.
'None of our sons or daughters will set foot on the bus until the advert is changed.'
A spokesman for the Dolomitibus transport company declined to comment.
The award for the most misguided sign however surely has to go to this road marker in Illinois, which warned motorists: ‘CAUTION! ZOMBIES AHEAD!’
