UPDATE

12/20: The event was a huge success, and brought in over $15,000 from the auction. With a matching donation from Credit Unions for Kids, the total donation to Children's Hospital Los Angeles came to over $30,000!

Randy Jackson is recreating an iconic piece of memorabilia "that only 3 people have ever seen in their lifetime," by putting his name on a martial arts weapon, and it's all for a good cause.

The former "American Idol" judge inked the sword as part of "The Night Time Show Holiday Special Benefiting Children's Hospital Los Angeles."

Comedian and show host Stephen Kramer Glickman tells The Blast he's a huge fan of the Will Ferrell and John C. Reiley flick, "Step Brothers," and was able to coordinate The Dawg signing a samurai sword as one of the auction's premier items.

The holiday special will also features appearances by Jon Heder, Jimmy O. Yang and "Modern Family" star Nolan Gould.

Along with the Randy Jackson sword, one of the other items expected to bring in a ton of dough for Children's Hospital L.A. is an exclusive Funko Dorbz Mickey Mouse doll, which comes in at a towering height of 5 ft.

The behemoth Funko doll is expected to fetch between $7,000 - $10,000. All proceeds from the event will go directly to Children's Hospital L.A.
