Hope this hasn't been on here before, but apologies if so.

Posh & Becks were driving through the country when their car broke down. It was raining heavily so they nipped into an old ruined house for shelter while waiting for the breakdown truck.

Posh badly needs a p*ss and asks Becks to look for a toilet. He goes off and comes back a few minutes later, by which time she's getting desperate.

"I've found a toilet, but I got some bad news, Posh - it ain't got no door".

Posh shoots back angrily:

"Then how the f**k am I supposed to get in?!"
