Gawd!
A pal of mine (an ex-roadie for UB40 and quite a character) got ditched by his GF and was rather upset about it, especially as she took up immediately with a flashy rich bloke. Still having a door key he went round and w@nked into her face cream, stirring it thoroughly afterwards. "At least I've got the satisfaction of knowing that every time that bastard kisses her he's kissing my billy bunk!" he told me.
