A dustman is going along a street picking up the wheely bins and emptying them into his dustcart 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 Chinese bloke answers... "Harro", says the Chineseman. "Alright mate, where's your bin?" asks the dustman "I bin on toilet" replies the Chinese bloke, looking perplexed. Realising the Chinese fellow has misunderstood, the binman smiles and says "No mate, where's ya dust bin?" "I dust bin on toilet I told you" says the Chinese man. "Mate" says the dustman... "you're misunderstanding me...where's your Wheely Bin?" "OK" "OK" , the Chinaman says, "I wheely bin having wank."
