The man known to the country as Joe The Plumber was ambushed at a campaign event in Ohio Sunday.

WLWT in Cincinnati reported that Joe Wurzelbacher made a campaign appearance with U.S. Rep. Steve Chabot, R - Ohio, and a group of plumbers who support Chabot's opponent approached Wurzelbacher.

Video shows how one plumber lost his cool and started taunting Wurzelbacher.

"Hey, Joe, get a license. Joe, get a license! Joe, get a license! Pay your taxes. Pay your taxes," the man yelled as a couple dozen people looked on.

A Chabot supporter ended up shoving the yelling protester out of the way and the two had to be separated by others, WLWT reported.

No one was hurt or arrested.

Court documents show Wurzelbacher owes nearly $1,200 in back taxes. Wurzelbacher, who questioned Obama during a campaign stop on Sunday, acknowledged he doesn't have a plumber's license, saying he doesn't need one because he works for someone else. But a city building inspection official says Wurzelbacher still would need to be a licensed apprentice or journeyman to work in Toledo, and he's not.
