Senator Obama's supporters are making a big deal of the fact that Joe the Plumber is unlicensed. It's now time to play the Messiah card:
Jesus was an unlicensed carpenter, and Brutus was a senator.
Ironically, the Romans were innovators in sewage management and plumbing. This probably put the crap hole diggers and clay pot carriers out of business. Apparently, they did not have a strong protectionist union.
