Hollywood 411 recently sat down with the star of the hit sitcom The Big Bang Theory, Johnny Galecki. Galecki starts off by explaining his character, Leonard, to people who don't watch the show.
Then, for fans of the show, Galcki goes on to explain how he prepared for the part and how he learns all those complicated science words for his Big Bang Theory quotes.
Our favorite part of the interview, of course, is when he teases at some Big Bang Theory spoilers and talks about his future with the beautiful Penny.
The interview is definitely worth watching, so please enjoy:
