A pair of Quebec radio personalities known for prank phone calls are boasting of another victim — the Secretary General of the United Nations.

Marc-Antoine Audette and Sebastien Trudel say they posed as Prime Minister Stephen Harper and were able to get Ban Ki-moon on the phone.

The so-called "Masked Avengers" say the diplomat was rushed out of an important meeting to speak to them.

They say Ban Ki-moon became confused when fake Harper complained he was too busy combing his hair with crazy glue.

Harper's spokesman tweeted about the prank — "well played."

The Avengers' past victims include former Bloc Québécois leader Gilles Duceppe, former American vice-presidential candidate Sarah Palinactor Charlie Sheen and business tycoon Donald Trump.
