San Francisco -- "American Idol" judge Paula Abdul urged California legislators to force nail salons to clean up their act, testifying Monday about her yearlong health ordeal after an unsanitary manicure. Abdul said a trip in April 2004 to a Studio City nail shop that used unclean equipment sent her in and out of the hospital, and made her the butt of late-night talk show jokes. "Being a professional dancer, I'm no stranger to pain, but this time the pain was so excruciating that even my hair touching my thumb caused me to scream,"
