If you're a fan of The Big Bang Theory you'll want to see this. Simon Helberg was on Conan O'Brien when he was asked what other impressions, if any, he does besides Nicholas Cage.

What he does with Al Pacino's quirky walk was spot on and so true. The 33 year old actor has something in common with Pacino. They're both only 5' 7" tall. Which maybe had something to do with Simon's interest in karate as a child. He became a black belt at only 9 years old!
