Patrick Dempsey showed up during testing for the Rolex Sports Car Series Rolex 24 at Daytona International Speedway Daytona Beach!
We've all known for a while know that PD is a huge fan of racing, but it's still kinda funny to see him in that full get-up!
Plus, why is he holding a skull??
We may never know.
Check out the rest of the pics below!
