A dustbin man knocks on a a guy’s door, looking for his rubbish / garbage / trash. The guy’s English isn’t great..

He opens the door slightly, with a red, sweaty face.

”Where’s yer bin?” asks the binman.

”Errr… I bin in barfwoom,” responds the bloke.

”No, mate: where’s yer BIN?” he asks again.

”I told you. I BIN in barfwoom..”

Getting exasperated, the binman says “Look - WHERE’S YOUR WHEELIE BIN?”

The chap’s shoulders slump and, crestfallen, he lowers his head…

”Oh, OK… I wheelie bin having a wank..”
