SAN FRANCISCO — Matt Damon is honored that the most recent celebrity of the presidential campaign _ “Joe the Plumber” _ dropped his name in an interview.

“That was a surprise. I hadn’t heard that Joe the Plumber dropped my name,” Damon said. “I’m honored to be in the little passion play, to be an extra.”

The plumber, whose real name is Samuel Wurzelbacher, became an overnight media sensation after he was referred to constantly in the final presidential debate. When the press arrived at his Ohio home, Wurzelbacher, a Republican, said he hoped he wouldn’t make a fool of himself with all the attention, “I don’t have a lot of pull. It’s not like I’m Matt Damon.”
