If you start to disrespect the character you're playing or play it too much for laughs that can work for a sketch it will sell some gags but it's all technique. It's like watching a juggler - you can be impressed by it but it's not going to touch you in any way.
I first fell in love with music when I was a little boy. When I first heard music I felt the beauty in it. Then being able to tap along on a table top and box was great but my favorite thing to do was to watch records spin. I would almost get hypnotized by it. These things are what drew me in initially.
