Boomhauer

Jeff Boomhauer, most commonly referred to as Boomhauer, is a fictional character in the animated series King of the Hill. The character is voiced by series creator Mike Judge, and is known for his nearly incomprehensible speech.

Boomhauer is the high school friend and neighbor of the characters Hank Hill, Bill Dauterive, and Dale Gribble. Although he introduced himself as Jeffery Dexter Boomhauer III in the 2000 video game, his first name was only spoken in the TV series during the 13th season episode, "Uh-oh, Canada", when the Canadian woman with whom he'd switched houses for the summer said, "Hello, Jeff. Oh my, it's the fifteenth already?". His driver's license as shown in the series finale reads simply "Boomhauer, Jeff".
