ah ... stout ....
fun stuff .......
when I was young and stupid, i played plenty of those silly drinks
game ....
a glass of stout .... a raw egg ..... spread a piece of tissue over
it, slip a rubber band around glass to hold tissue in place ....
10cent piece in the middle, and people taking turns to burn holes
into it .... ashes drop into the glass .......
anyone who plonks the coin into the glass has to drink up
everything ... ashes and all ... 
(and yes ... stout has aphrodisiacal properties .....
)
