In the mid 1980s, CBS anchorman Dan Rather was attacked while walking along Park Avenue to his Manhattan appartment. His assailant kept punching him and asking a question. What was the question?

"What's the frequency, Kennedy?"

(also an REM album title)

I believe it is actually "What's the Frequency, Kenneth?', and his assailent, William Tager, later killed a stagehand outide the NBC "TODAY" show set in NYC.

Thanks Sailracer. I actually wavered between Kenneth and Kennedy but decided Kennedy sounded more "right."

As pointed out, Kenneth is right. Poor Dan seems to have a history of strange things. In 1968, he was assaulted and knocked to the floor by apparently a type of 'security guard' at the Chicago Democratic National convention. The punch was seem on national TV. A few other 'odd' events surround him over the years.
