Jeff Dunham's life is an open book. And in that book ("All By My Selves -- Walter, Peanut, Achmed and Me") you learn stuff like:
■ He's obsessed with helicopters. Really.
■ The hardest letters for a ventriloquist to do without moving his lips are F, M, P, V, W and Y.
■ His parents bought him a $1,200 suit for his first Johnny Carson show, but then he got bumped.
But he's doing fine now, returning to the Colosseum at Caesars Palace at 8 p.m. Saturday. Tickets are $54.50-$94.50 for the show at 3570 Las Vegas Blvd. South. Call 731-7333.
