A refuse collector is driving along a street picking up the wheelie bins and emptying them into his compactor.
He goes to one house where the bin hasn't been left out, and in the spirit of kindness, and after having a quick look about for the bin, he gets out of his truck goes to the front door and knocks. There's no answer.
Being a kindly and conscientious bloke, he knocks again - much harder. Eventually a foreign guy comes to the door.
"Harro!" says the man.
"Gidday, mate! Where's ya bin?" asks the collector. "I bin on toiret," explains the bloke, a bit perplexed.
Realising the little foreign fellow had misunderstood him, the bin man smiles and tries again.
"No ! No ! Mate, Where's your dust bin?" "I dust been to toiret, I toll you!'' says the man, still perplexed.
"Listen," says the collector. "You're misunderstanding me. Where's your 'w h e e l i e' bin?'"
"OK, OK. " replies the resident with a sheepish grin, and whispers in the collector's ear.
"I wheelie bin having sex wirra wife's sista!"
