All these years and Fallon still can't control himself from laughing at the camera.
I'll never understand his appeal, he always sounds to me like he's forcing a childlike charm.
Fallon represents the new male. He's an adult who acts like a child, an awkward adolescent in a middle aged man's body.
He doesn't seem like it, but Fallon is almost 40 years old. He's about the same age as Leno when he took over.
