Throw in a bottle of White Lightning and you are sorted,
When was 18, I worked in a pub, and we got some promotion 1.5 pint hieneken glasses.
You could fit in a bottle of Special Brew, A bottle of Barley Wine, and a bottle of White Lightning a dash of black current , it was horrible, but got you steeeeeeming ! It was the drink of choice for about a year, between me and a few mates who all had out own 1.5 pint glass behind the bar -
