Comedian-actress Lucille Ball is home and feeling fine after undergoing minor surgery last week to remove a cyst on her thyroid, Wanda Clark of Lucille Ball Productions said Monday. Ball, 76, the star of slapstick television comedy in the 1950s and 1960s, went home Friday after three days in Cedars-Sinai Medical Center. "She was in the hospital for some very minor surgery and she's just fine," said Clark. "She's going about her normal business--there's nothing to even recuperate from." A Cedars-Sinai spokesman said the actress had been in the hospital for her annual physical exam.
