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 Japanese bloke answers... "Harro", says the jappy chappy.
"Alright mate, where's your bin?" asks the dustman "I bin on toilet"
replies the Japanese bloke, looking perplexed.

Realising the Japanese 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
Japanese man "Mate" says the dustman... "you're misunderstanding
me... Where's your Wheely Bin?" "OK" "OK" , says the Jap, "I wheely bin
having wank"
