Barney Stinson

If Barney Stinson's not the top contender in the 'Greatest How I Met Your Mother Characters of All Time,' then we've all been living under a rock. Seriously, who else could pull off a playbook with a move called 'The Lorenzo Von Matterhorn'? Only Barney makes wearing suits look like a survival skill and not just a fashion statement. Fans are torn: do we love to hate his antics, or hate that we love them so much? It's the kind of dilemma that keeps you up at night, arguing with friends till the sun comes up.
