The larder of innocent, functional things which resemble human genitalia is ever growing.
Take this tourist map of a Hertfordshire town, which is enjoying a flurry of publicity thanks to the fact it is shaped rather like a penis.
Commissioned by the Canal and River Trust, the colourful diagram guides visitors around Berkhamsted and doubles as fodder for dick jokes on social media.

A spokesman for the trust said the shape of the map had not been noticed until it was pointed out by members of the public.
He told the BBC: “This is one of about 100 maps we’ve been promoting.
“You could accuse us of being a bit naïve but canals are long, straight things, and when you draw a map it tends to be that sort of shape.”
A further rogue penis appeared via Google Earth last year in the guise of a Merseyside estate, with resident Carl Hodge admitting: “You can’t argue because it really does look like just a man’s cock and balls.”

It was also recently realised the stadium where Qatar will host the World Cup in 2022 resembles a vagina.

A vertical slit and symmetrical wrinkles serve only to enhance the likeness of the Al-Wakrah building to the female genitalia.
