He needs an original idea, too. Seriously. Don Novello (aka Father Guido Sarducci) did this about twenty-five years ago; wrote goofy letters to all sorts of public figures, and then published the letters and their replies in a book. I remember that it was pretty funny too, unlike Al Franken...
One lady sued numerous public officials and the president of a local department store because her parents' house was condemned for an interstate back in 1950 (she was about 30 years too late to do anything about that). She sent us copies of many letters from elected officials and archbishops all over the country (she was a Catholic convert) and their polite but puzzled replies.
Finally one Christmas she sent us a card informing us that some Fathers up in New York state somewhere were saying a daily Mass for the souls of the United States District Court for the Northern District of Georgia, Atlanta Division. The judge said he thought about writing her back and telling her we couldn't take gifts from litigants, but decided that "we needed all the praying we could get." So we never said anything about it. She eventually got tired and went away, IIRC.
That was The Lazlo Letters, right? A lot of people have done the same thing and published the results over the intervening years; there's even a Freeper who has a website devoted to his own Lazlo-like correspondence with various companies. But nobody's ever bested Novello, I don't think.
