Matthew Perry is my second favorite. He was recently knocked out of the top spot, but still provides lots of competition.
I discovered him when I discovered "Friends", after a co-worker told me how much I reminded her of "Monica on Friends". Personality-wise, that is.
Not only did I discover the character of Chandler Bing, but I found a new favorite tv show. I had avoided it for so long because it was "popular" and I didn't want to be associated with that. Now I see what a great show it is.
Matthew says that Chandler is an exaggerated version of himself.
Matthew is good looking, but his personality seems to shine way more than that. He seems like a genuinely good person. That's really refreshing.
Not to mention that he could probably leave you in stitches.
