Friday at the "Little K," celebrities battled it out in a charity Wiffle ball game as part of the third annual Big Slick celebrity weekend in Kansas City.
Big Slick was founded in 2010 by Julie and Mark McKee, Gloria Rudd and Kathy and Dan Sudeikis to raise money for Children's Mercy Hospital. With help from Paul Rudd, Jason Sudeikis and Rob Riggle, the organization has raised more than $330,000.
This year, the celebrity weekend will help fund a new cancer center offering cutting-edge treatments and expanded facilities. In addition to the Wiffle ball game, celebs will participate in a poker tournament and an auction.
Riggle, Rudd and Sudeikis -- who are all Kansas natives -- were joined Friday by Jon Hamm, Eric Stonestreet, Olivia Wilde and many others. And when they got near the TV cameras, hijinks naturally ensued.
