I'm Talking To The Juice Box Guy!
Last week, before a Boston Red Sox/Kansas City Royals game, Will Ferrell threw out the first-pitch at Fenway. He did so wearing a retro Luis Tiant jersey, and impersonated Tiant perfectly. I found the video of it on YouTube, of course, as well as some other classic Ferrell sports moments. Enjoy!
And here is Ferrell as Harry Caray in Space: The Infinite Frontier.
