After a caller yesterday amused radio host Rush Limbaugh with a comparison between Senator Barack Obama and beloved icon of children's literature Curious George, the radio host returned from a break and immediately apologized—no doubt at the behest of frantic staffers who somehow realized that noting a resemblance between an African-American man and a monkey might even be too racist for Rush Limbaugh's show. Limbaugh swore that he had never heard of the Curious George character ("I never heard of Curious George until that caller. I don't care how old Curious George is. I never heard of Curious George. I had no idea what she was talking about. Now they tell me Curious George is a monkey. ") and blamed his laughter at a joke involving someone he claims to have never heard of on the fact that he was "sick," presumably with that bigot flu that's going around. [Politico]
