pic reminds me of a story my dad often recounts. In his day they used to go to village pubs by motorbike, have a few swifties and move on. One day he was having a pish in the loos. The loos were the old type with full length trough going to a sinker. As he's pishing, some old boy is there singing away (even more pished) and his false teeth fall into the sinker. OId boy swears a bit, then rolls his sleeve up, retrieves his teeth and pops em straight back into his mouth - no washing or rinsing.
Probably his alternative to the after-beer curry.
