The Best South Park character

There are several characters to choose from, and a bit of research shows that Butters is the concensus among internet input. But I'd have to disagree with that, and say that hands down Kenny McCormick is the funniest.
We can almost never understand what the f*ck he's saying. Since most of Kenny's lines are unintelligeable, the show has no reason to portray him interacting with anyone unless it's part of a gag. As far as the show is concerned, Kenny is nothing but a walking comic. It's funny not only to see the kids' reaction to his monologues, but also to hear someone else occasionally repeat his lines. You can almost always count on a lesson towards the end of an episode, which is usually recited by Kyle or sometimes Stan. Although this is a big part of the show, their lessons sometimes lack in humor. Kenny however has no part in this, either because he's dead, or also because he muffles.
Being is the most sexually knowledgeable of the boys, they often turn to him for clarification, which is again funny to hear his muffled monologues and their subsequent reactions. Once when asked to go get chicks for a clubhouse party, he did what most of us in 4th grade probably dreamed of: he finds two skanky teenagers who are ready to party. He is usually the only one who actively tries to get action.
He is often ridiculed for being poor. One look inside his house would make you think that his parka is made of his own bedroom curtains. This not only causes a fun dynamic between the 4 boys (they often dread going to his house), but also explains circumstances for plot purposes (only poor people get head lice).
He is usually the one to experiment with different things and is not afraid to take a dare. He is seen sniffing alien cocaine when the other boys are afraid, or will eat unmentionable things for money. He is very bold, and yet calmly cool about it.
Then there are his numerous deaths. Most of the time he dies just because, but a lot of the time he usually dies attempting some heroic stunt or self sacrifices for the good of others. This proves that, like Stan and Kyle, he is more interested in being a good person than he is in himself.
Oh yeah, and he's blond. I remember the first time I saw his blond hair, it totally blew my mind.
