Dangerfield undergoes heart surgery

American funnyman Rodney Dangerfield entered a Los Angeles hospital on Tuesday in preparation for heart valve replacement surgery.

The ailing Caddyshack star, 82, underwent brain surgery last year to reduce the chances of having a stroke during the operation today.

Before entering the hospital, Dangerfield said: "If things go right, I'll be there about a week, and if things don't go right, I'll be there about an hour and a half."
