Don Tjernagel, born and raised in Waterloo, Iowa, has been doing stand-up comedy since 1997. As a young man, Don played football until sustaining a serious injury during spring practice at the University of Northern Iowa. Don decided to try stand-up on a whim in 1997. Not too long after that Don’s popularity led him to do a show in several Las Vegas clubs such as the Casino Royale Volcano Lounge, Bourbon Street Hotel, The Monte Carlo and the Las Vegas Hilton Hotel.

With the start of his first show at the Casino Royale, Don became the youngest comic to star in his own show on the Vegas Strip. In August of 2003, Don wrote a book about his travels through the country as a comedian. The book, called American Infidel, detailed his observations as a comedian and American citizen (mostly writing about his sex life and women in general, while simultaneously expressing his views on the First Amendment). Don started to record his stand-up in 2008 with his first DVD release, Smut.

Don continues to record his stand-up on both DVD and CD. His latest release was the The Worst of Donzilla 
which was released on August 2, 2012
