"Who told you I was Bozo?" he wanted to know.
"Your son," I said, at which point he confirmed that yes, he was Bozo, but not an official, full-time certified Bozo, more of a part-time Bozo.
"To be an official Bozo, you had to go to a special school in Texas," explained Mr. O'Donnell. He never did. Instead, he was asked to fill-in for the official Bozos whenever they would have to travel out of the Philadelphia area for acting gigs.
"They would leave, I would come in and work for two or three weeks, whatever, until the regular Bozo came back," Mr. O'Donnell said. "I was the fill-in Bozo."
The TPM Poll Average of the Delaware Senate race has the former part-time Bozo's daughter Christine O'Donnell -- who many comedians and bloggers have depicted as something of a bozo herself -- trailing Democratic nominee Chris Coons by 55.0%-39.6%.
