The Wheelie Wheelie joke ;-)
A garbage collector is driving along a street in Australia 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 Japanese man comes to the door. "Harro!" says the Japanese man.
"Gidday, mate! Where's ya bin?" asks the collector.
"I bin on toiret," explains the Japanese bloke, a bit perplexed.
"No! No! Mate, Where's your dust bin?"
"I dust been to toiret, I told you!" says the Japanese man, still perplexed.
"Listen," says the collector. "You’re misunderstanding me. Where's your wheelie bin"
"OK, OK” replies the Japanese man with a sheepish grin, and whispers in the collector’s ear. "I wheelie bin having sex wiffa wife's sista!"
