Every year, Randy and Billy raise money for SlamT1D — a non-profit that helps kids and families battling type 1 diabetes. This year, they had a simple thought: “What if we played wiffleball for 24 straight hours to raise money?”

Patrons are invited to join Randy and Billy on the field for a small donation. Fans can also donate directly to them via a website, as well as watch live on YouTube for all 24 hours.

WiffleMania will also include a “Wheel of Chaos” — donate $50 and the duo has to spin the wheel. On the wheel will be a variety of “curveballs” that the duo will have to abide by for a set amount of time. For example, they may have to pitch & hit with their non-dominant hand, swing only pool noodles or play with “juiced” wiffleball bats.

For $100? You can PICK whatever you want off the Wheel of Chaos for them to do.
