He played Charlie, Jim Carrey's sidekick in The Mask. His is the voice you hear in the Office Max commercials. He even starred in a short-lived sitcom on UPN. But Richard Jeni is at his best when he's performing standup, which he'll do tonight at the Carefree Theatre in West Palm Beach. The Brooklyn native supplies audiences with a cast of wacky characters and plenty of observational humor, such as: "Carjacking is so bad, I'm driving with the Club on." Jeni's resume also includes a few HBO specials and a job as host of Caroline's Comedy Hour on A&E. His live show begins at 8 p.m. at Carefree Theatre, 2000 S. Dixie Hwy., West Palm Beach. Tickets cost $24.75. Call 561-833-7305.
