Vanna's been turning letters and tapping touchscreens for Pat Sajak on Wheel of Fortune since 1982. She smiles, wears tiny dresses at age 53 and is a darn good clapper. That was apparently enough to give her a spot on Hollywood Boulevard in April 2006. O.K., so she also wrote an autobiography in 1987 and had a few random cameos on Full House. In 1992, the Guinness Book of World Records named her the "world's most frequent clapper." Of such things is a star born.
