I once had a half pint of Toby bitter....only for a dare mind!

Maybe not the strangest drink but it made me do strange things like ask God to take me out of my misery.

Caipirinha's in Rio made with the strongest cachaca made, 6 of them and you can fly and crash hard.

a) a barley mead scooped from a rusting barrel in rural Africa: bland ditchwater aroma and taste (but enough alcohol to kill the flies and bees floating on top). I had to be sociable in front of village elders.
b) a 180 proof rum smuggled out of the Wray and Nephew distillery in Jamaica. It gave new meaning to the term rum punch.
c) a yogurt-based Iranian drink (doogh) that was very refreshing in hot Esfahani summers: so enjoyable in fact that after sipping 5 large glasses I contracted lactic acid poisoning.

A cup of "tea" that a Tibetan monk gave me in a monastery. It contained yak fat and salt and sometimes I can still taste it, 8 years later.

Some offering in Chendu at a wedding party. Sweet Chinese strong whisky drink which was served from a huge glass decanter containing a snake.

Don't you just hate it when you are at a party and leave your can of beer for two minutes and some sad bastard uses it as an ashtray?

I used to live in a village in Switzerland and a local farmer would invite people round to pick his apples and pears. He would then take your fruit and distill it for you. So you would have a few bottles of hooch. That stuff would blow your head off. We used it to light the barbecue.  And give it to unsuspecting visitors.
