4. Tanner - The Bad News Bears
There are few things in this world funnier than a small child with a mouth like a sailor. Plenty of the characters from The Bad News Bears could have filled this role, but little Tanner is the one who really does it justice. There's just nothing like a tiny little blond kid spewing racial slurs and generally being politically incorrect as hell. And picks a fight with just about anyone, anywhere. He might mock them incessantly, but he's loyal to his teammates -- and he'll kick your ass if you mess with Lupus. Walter Matthau is hilarious, Tatum O'Neal is precocious, Jackie Earle Haley is badass, but Chris Barnes as Tanner is
priceless. And that's the end of the matter.
