A very bad thing has happened. Yuk.
I went out for a bite of dinner with the excellent stand-up comic, my mate Mike Wozniak. We went to Highgate, which is nice. The journey home involved walking to Archway, which is horrid. We stopped for once last drink at The Lion pub.
When Mike's pint was finished, an older (but not obviously trampish) chap came over and gave him a pint of Carling. "Here - it's for you", he wheezed. "I bought it for my friend, but he's left now... It's clean".
Obviously we discussed whether or not Mike should drink it - particularly in view of the "it's clean" comment. Mike drank an inch or so before he noticed that the man was doing something odd with his own pint of Guinness. With a syringe.
The man was performing the following routine:
1. Drawing up 20ml of Guinness from his glass into a syringe
2. Injecting the Guinness up a catheter tube and through his exposed cock
3. Waiting a minute or so
4. Drawing the Guinness (plus wee and bladder sediment presumably) back into the syringe
5. Squirting syringe back into pint
6. Drinking from pint glass
We assumed - presumably correctly - that he had used the same bladder irrigation technique for Mike's pint. Mike made himself vomit, and we spent the journey home discussing the possible diseases that could have be transmitted.
