Comedian Rich Little tailored his act to fit his audience while visiting young hospital patients in Reno, Nev.

Instead of doing his trademark impressions of Richard Nixon, Ronald Reagan and George Bush, Little did Kermit the Frog and the Cookie Monster.Little, who's appearing at Harrah's Reno, said he had to change his act at Washoe Medical Center because many young people have not heard of him or the people he's famous for imitating.

"The kids don't know who I am," he said last week. "The nurses will be falling about and the kids are looking at me like I should be locked up in a bed somewhere."
