I remember as kids there was also one scrounging kid on the estate who always begging off others. "Gis a drop of that can", "Gis a chip" "After you on that..."
So to teach him a lesson we pissed in a half empty bottle of Fanta before we played a game of football up the park and when we stopped for a break he was first in there as expected, "Gis a drop of that". He took a big old guzzle and didnt even realised he had drank piss, until someone pointed it out. He quite enjoyed it too
Hes dead now. Died before he was 30. Alcoholic. Should have stuck to piss.
