Rachael admits to not being a good skater, but her guest Denis Leary is right at home on the ice. In fact, the star of Rescue Me tells Rachael that he has a hockey rink in his own backyard, which means he gets to make the rules when playing with his firemen friends. "I'm 50 years old now," Denis says, "so when I play against a 25 year-old fireman, who is much younger and faster than I am, I'm allowed to trip people. I don't call it playing dirty; I'm 50, he's 25 -- I think it's just called evening the playing field."

When Denis shows Rachael how to shoot a puck, he learns that he's on her turf now and she gets to make the rules. "If you can put 10 of these pucks into the net," she tells Denis, "Sara Lee is going to give you $1000 for each one you get in to go to the Leary Firefighters Foundation. And I'm going to personally match dollar for dollar the same amount."

"Now you're putting pressure on me," a shocked Denis says, "because I actually have to get them into the net!" Can he do it? Check out the video to find out!
