For my entire life, I've been a huge fan of Saturday Night Live. It's been my dream to go see it live in New York, but sadly...that has not come true (yet). However, several years ago, I was in New York City and took the NBC Tour at Rockefeller Center which includes at top of at the SNL studio where we actually got to see the cast rehearsing for that weekend's episode. As the tour was wrapping up, our group went down the elevator and suddenly, we realized that cast member Bill Hader was in the elevator with us! He was super nice as was always one of my favorite cast members!
I ran across this interview Hader did a few days ago with Conan in which he NAILS this impromptu impression of Arnold Schwarzenegger.
