Hands up those whe managed to pour a double gin into a complete (and I mean complete) pint of Guinness? This was a well known (in certain circles) Stirrup Cup and I think the prerequisite was that you had to have already mounted.....

Presumably falling off was a lot softer afterwards.

I used to occasionally imbibe in my, then car(e)less youth and never got past two pints. plobably the reason I can't remmemberrdiddly squich amnymorr.
Happy St Patrick's day again. cheers
