Hollywood legend Paul Newman (search) had a bucket of spaghetti dumped over his head Thursday as he played the clown for a group of sick and disabled children.

The star made a guest appearance at Zippos Circus (search) to entertain the 300 youngsters, who have all been helped by groups aided by funds from his "Newman's Own" spaghetti sauces and and other products.

Dressed in a green bowler hat, outsize bowtie and giant, yellow clown shoes, the 79-year-old star delighted the crowd with his 10-minute slapstick routine, which also involved sitting in a large cream pie.

"I'm not by inclination a clown. This will certainly end my professional career," he joked before the show.

Aptly for a man who starred in the cowboy classic "Butch Cassidy and the Sundance Kid," Newman's name for the occasion was Butch Bolognese.

The actor started the not-for-profit "Newman's Own" in 1982 and has so far donated more than US$150 million to charities around the world.
