An individual named Samuel Joseph Wurzelbacher who was the surprise star of the final 2008 presidential debate between now president-Elect Barack Obama and Republican Senator John McCain as a feeble attempt at defeating Barack Obama during said debate. He was made famous by questioning Barack Obama's proposed tax policies, which was blown completely out of proportion and twisted out of context beyond recognition by the McCain campaign and the FOX News corporation. He was also made infamous for being an unlicensed plumber who owed back taxes to the IRS, which was never mentioned by the McCain campaign.
Joe the plumber is a useless tax deadbeat. He isn't even a licensed plumber!
