Senator John Kerry made the term botch a dominant part of U.S. vocabulary recently by being a prime example of a botcher

On Tuesday, October 31, 2006; Democrat Senator John Kerry of Massachusetts, told a group of students in Pasadena, California:

"We're here to talk about education, but I want to say something before—education, if you make the most of it and you study hard and you do your homework and you make an effort to be smart, you—you can do well. If you don't, you get stuck in Iraq."

Kerry subsequently insisted that he "botched" the delivery of the joke; he meant to say, "You get US stuck in Iraq; just ask President Bush."

"Of course, I'm sorry about a botched joke," Kerry said Wednesday (November 1, 2006) on MSNBC. "You cannot get into the military today if you do badly in school." He accused President Bush of twisting his words.
