A bloke has had a huge dry spell and is gaggin for it, so he's passing a drunk passed out on a park bench and decides to have his way with him. The drunk doesn't wake up and the guy feels a bit guilty afterwards so he drops a tenner under his head where it's laying and leaves him be. The drunk wakes up finds the tenner and thinks all his Xmas's have come at once and heads to the offie. He buys a case of cider and then back with him to the park to his usual bench.
The dude is passing later that evening and sees him on the park bench again, he see's he's passed out surrounded by empty cider tinnies, so off he goes again.
Next day the drunk wakes up, gets another case of cider, same thing again.
Next day the drunk heads down the offie, he walks in and the offie blokie says "same as usual" and motions towards the cider, the tramp says"na I'm switching to Guinness, that cider is burnin the hole off me".
