"The guy from F-Troop, Sen. Ben Nighthorse Campbell." (This is a reference to the zany Indian characters on the 1960s TV sitcom F-Troop. They had names like "Roaring Chicken," "Crazy Cat," and "Chief Wild Eagle.")
"I didn't know that Allan Bloom was coming in from the back end." (The homosexuality of the author of The Closing of the American Mind became widely known when Saul Bellow published Ravelstein, a novel whose protagonist was based on Bloom, who by then was deceased.)

"Janet Reno's having a press conference. Ms. Reno, of course, has Parkinson's disease, has a noticeable tremor. […] I don't know how she gets that lipstick on (laughter) looking like a rodeo clown."
Every one of these statements came directly out of Imus' mouth on his program.

It's safer that way.
