U.S. comedian and entrepreneur Jeff Foxworthy has signed on to appear in three episodes of the reality series "Shark Tank," ABC said Tuesday.

The network announced it also has ordered eight additional episodes of the show, which it says gives "budding entrepreneurs a chance to make their dreams come true and become successful -- and possibly wealthy -- business people."

The aspiring entrepreneurs must first try to convince five tycoons to part with their own cash and give them the funding they need to jump-start their business ideas.

"Enter the Sharks of 'Shark Tank,' self-made successful business people whose own entrepreneurial dreams came true," ABC said in a synopsis. "The five Sharks are real-estate mogul Barbara Corcoran, 'infomercial' industry pioneer Kevin Harrington, technology innovator Robert Herjavec, fashion icon Daymond John and financial expert Kevin O'Leary."

Joining the panel of Sharks for three episodes will be comedian Jeff Foxworthy. A self-made successful businessman in his own right, Foxworthy expanded his popular work in stand-up comedy into an empire of albums, books, hit comedy tours, and forays into television and radio, including his current work as host of 'Are You Smarter Than a 5th Grader?'"

"Shark Tank" is to return to production this fall and will air in 2011.
