Rach and her celeb pals are suiting up as firefighters for a day! Denis Leary is putting them through scenarios faced by real-life NYC firefighters at his firefighter challenge charity event. Plus, Rach has a big surprise for a powerhouse group of 9-1-1 dispatchers, and she's in the kitchen making a twist on fish and chips. (Salt and vinegar potato chips, anyone?!)
