If you ask Keith Olbermann, Rob Ford is the worst person in the world.

Toronto’s mayor was featured in Olbermann’s Worst Persons segment of his Countdown program Friday for his behaviour when he called 911 after his encounter with This Hour has 22 Minutes’ Mary Walsh.

“The new conservative executive (in Toronto) has had a rough start but never was it rougher than Monday,” the political pundit said.

Early Monday morning Ford was approached by Walsh, in character as Marg Delahunty, on the driveway of his Etobicoke home. Ford then called 911.

The CBC, citing anonymous police sources, reported that Ford said, “You ... bitches! Don't you f---ing know? I'm Rob f---ing Ford, the mayor of this city!”

Police Chief Bill Blair has since said that these reports are inaccurate, and that Ford never used the word “bitches.”

Olbermann read all but the first remark on-air as he railed against Ford and named him the worst person in the world, edging out Glenn Beck.

“Toronto’s Rob effing Ford The mayor of his effing city. Today’s effing worst person in the effing world,” said Olbermann in conclusion.

Ford, who is now in Guadalajara, Mexico, for the closing ceremonies of the Pan Am Games, could not be reached for comment.
