Here's some more quotes from your buddy:
It's a song so obscene that 60 Minutes could play only part of it on television. "She goes to state dinners with her lesbian friends, makes big investments with high dividends. Forgets to pay taxes but then makes amends, that's why the first lady is a tramp," the lyrics went.
"This is the first lady of the United States. Doesn't worry you at all?" Wallace asked Imus.
"That's not offensive," Imus replied.
"Well, shall I play some more of it, where it gets really offensive?" Wallace asked.
"Well, there is a line, there are a couple of lines in there that were over the line. Yeah, I mean, that was a mistake," Imus acknowledged.
"And drug addict. You know, I'd drink on the air. I'd do cocaine on the air, you know," Imus admitted in the interview.
