His voice occasionally cracks, especially when he's excited... which is often. There's an endearing, boyish quality to it, like he's always on the edge of laughter. He's the kind of guy who can't resist making dumb puns; the worse they are, the prouder he gets.

He delivers them with a mischievous grin and a barely-contained giggle, he's amused by his own sense of humor. Even when no one else laughs, he does and somehow, that makes it even funnier.
