Jay Leno joked during his Tonight Show monologue on Wednesday night, "More problems today for Paris Hilton in prison. Apparently she saw another woman wearing the exact same outfit that she had on. ... Paris Hilton has now been without a man for six days. She's broken George Michael's old record. ... Paris Hilton said in an interview with Barbara Walters that she will no longer act dumb. So apparently she's taken a vow of silence."
