Late-night comics target Bush:

Perhaps sensing vulnerability, the late-night comics have been piling on President Bush.

During the first three months of the year, Bush has been the punch line of 307 monologue jokes by Jay Leno, David Letterman and Conan O'Brien, according to the Center for Media and Public affairs, which studies this sort of thing.

That compares to 197 jokes during the same period last year. For all of 2005, the center's statisticians counted 544 Bush jokes.
