A dustbin man had just started his new round.
He came to the house of a Japanese chap, who hadn't left his bin out.
So - he knocked on the door of the Japanese chap. It took a while for the Japanese man to answer the door - eventually the Japanese chap answered the door:
"Where's ya bin" said the dustbin man
"I been to the loo" said the Japanese chap
"No, where's ya dustbin" said the dust bin man
"I just been to the loo" said the Japanese man
"No, where's ya wheelie bin" said the dustbin man
"O.K." said the Japanese man "I really been wanking"
