To celebrate National Wear Your Pajamas to Work Day, the crew members from Front Row Motorsports donned their favorite sleepwear emblazoned with their favorite cartoon superheroes and went to work.

The team was trained by Roush Fenway Racing and usually supports Chris Buescher in the NASCAR Sprint Cup Series, swapping rubber on his No. 34 Ford Fusion. In this video, the crew works on a Roush Mustang. The clip and the pajama day raise funds and awareness for the Casey Cares Foundation, a charitable organization that aims to lift the spirits of everyone affected by childhood illness.
