We are happy to welcome guest celebrity blogger Hunter Foster, who was Tony-nominated for his performance in Little Shop of Horrors. Foster, who is currently playing Sam Phillips in the new musical Million Dollar Quartet, will blog for Playbill.com all week; his fourth entry follows:

It's 8 AM and I am off to play softball for the Million Dollar Quartet/Addams Family team. Love the Broadway Show League. It's taken my legs about a week to recover from last week's game but I think I'll be fine. All I know is that if you saw Million Dollar Quartet over the weekend and Sam Phillips was walking gingerly, with a slight hitch in his gait, that was because old man Foster played Softball last Thursday and pulled every little muscle in his "gams."

Some of my favorite memories of playing for the Show League over the years include when we were doing the Grease revival — the first Grease revival. Like when Rosie O'Donnell got in a fight with our left-fielder because he went after a ball and ran over our second baseman, whom Rosie happened to be dating at the time. Or Adrian Zmed telling me he had a friend who wanted to play for us that year and lo and behold who shows up? Meat Loaf. First time in my life I've ever got the chance to say this: "Nice catch, Meat." Or our Pink Ladies, who would all show up in cut-off Daisy Duke blue jeans and high athletic socks only to flirt with the umps and talk dirty to the opposing batters.

I remember once playing against Iceman Cometh and Tony Danza was pitching and we insulted him mercilessly....Well, maybe it was just me: "C'mon, Tony, show 'em who's the boss!" That went over well. When I finally worked with Tony in The Producers, I told him about that day and how I yelled out that witty bit of trash talking. He looked at me with a cold stare and replied, "You're the guy. I've been looking for you all these years." Oops. You don't want to upset Danza, he's a boxer for heaven's sake! I laughed, uncomfortably, and said, "I'm just kidding. It wasn’t me. It was O'Donnell." He didn't say anything but just walked away...

Did he buy it? Well, he never mentioned it again, but I could have sworn that day when I told him it was O'Donnell, I saw a flash of fear in his eyes.
