What's a good book for a man in his 30's (something that would be fictional, fun, racey, and entertaining)?

I'm not a man, but every man I've introduced these books to loves them: What's Eating Gilbert G? by Peter Hedges (VERY funny and is written from a male perspective, first person, a little racy) and Catch-22 by Joseph Heller (funny and absurd, but not really romantic--it's about a pilot in WWII who pretends to be crazy to get kicked out of the Air Force). Then, there's The Catcher in the Rye, but he may have already read that.
