I have to say I have done some rum things especially when younger and pissed up. I along with several others showed our arses on the M6 to the City team coach that wizzed passed us after the Ipswich semi final at Villa Park.
On another occasion I had found a deserted beach in Rhodes and saw fit to indulge with a Dutch bird only for the 18-30s party boat to go sailing past and responded to the inevitable cheers by leaping up and bowing.
However flashing to the neighbours is something I would not consider on several grounds...arrest being one of a considerable list of reasons I would find this activity unwise.
What would you do if a six foot five bloke knocked on your door informing you he would like to accept your clear invitation?
