At the Downtown Hotel in Dawson City in the Yukon, they make a drink called the SOURTOE COCKTAIL. It contains a severed human toe (frostbite victim, if memory serves). You chug the drink, taste the toe and return it to the barkeep... you get a certificate saying you did it.
And a bad case of Athelete's Tongue.
Well, I have sucked on my husband's toes, so I guess I have literally sucked toe. I am not sure I would do that on a total stranger though. You never know where the toe has been.
