Sen. Al Franken makes a cameo appearance in the new memoir by Karl Rove, the one-time White House consigliere who was once famously described as "Bush's Brain."

The book, even before its publication date, already has Beltway inhabitants buzzing. As first recounted Thursday in the Washington Post, Franken accosted Rove (who he once called "human filth" at a black tie dinner long before he became a Senator.

According to the Post, Rove writes that Franken approached him and said, "I'm Al Franken. I hate you. You hate me." Rove writes that he told the "Saturday Night Live" star he didn't know him so couldn't hate him. "When Franken realized his line didn't inflame me, he scampered off to use it on former deputy secretary of defense Paul Wolfowitz -- who told the obnoxious comedian to [perform an impossible sexual act]."

Both Time and Newsweek reported on the Franken-Rove encounter and Franken wrote about it in his book "Lies and the Lying Liars Who Tell Them." The book describes a slightly different encounter with Wolfowitz, but doesn't specifically refer to the "I hate you" exchange. He later said he and Rove just "gibed each other a little.")

Franken spokesgal Jess McIntosh said her boss isn't offering up further comment on his meeting with Rove.
