Dallas ? Turns out that Joe Plumbers are sprinkled all over the country.

At least one is already better off, thanks to references by presidential candidates John McCain and Barack Obama to Ohio resident Joe Wurzelbacher – now famously “Joe the Plumber” – as they debated tax policies Wednesday night.

Phones rang off the hook Thursday in the Amarillo office of plumber Joe Francis, whose Web site joetheplumber.com became an instant Internet curiosity the day after the final presidential debate. About 1,200 miles from the Ohio plumber, Francis found his business suddenly in the spotlight.

Entrepreneurs hoping to cash in on a quick buck called about buying the Web address. Many others want T-shirts with the company logo, featuring a droopy-eyed cartoon plumber revealing the ubiquitous “plumber’s crack” above his pants.

While Francis was weighing that option, Joe Griesbach was signing autographs and granting television interviews in southern New Jersey, according to The Press of Atlantic City. He goes by “Plumber Joe” – the name painted on the side of his van.

And in Oxnard, Calif., plumber Joe Lara said the debate prompted a flood of phone calls to him, some from as far away as London, the Ventura County Star reported.
