When I was little Egon was my favorite Ghostbuster, largely due to the cartoon show. I was friends with a couple of twin brothers and I would go home with them after school and watch the show on the little 6 inch black and white tv screen in their room. I had a great time.
Anyway, I liked Egon best because he was so smart and usually had a good handle on the situation. He came off as a bit more of a 'nerd' in the movie to me though.
