A bin man is going along a street picking up the wheelie bins and emptying them into his dustbin lorry. He gets to one house where the bin hasn't been left out, so he has a quick look for it, goes round the back but still can't see it,…. so he knocks on the door. There's no answer, so he knocks again. Eventually a little Japanese bloke answers … ‘Harro’ 'Alright mate,…. where's your bin?' 'I bin in the toilet having pee' 'No mate, where's your wheelie bin?' 'OK, I wheelie bin having wank'
