You know him as:
Howard Wolowitz, self-styled ladies' man
Why we like him:
While Jim Parsons gets all the awards and Kaley Cuoco gets all the looks, Helberg delivers as many laughs as anyone on the show. As Howard, Helberg is exceptionally good at having no idea at to what is appropriate behavior around women. You'd think things would change now that Howard is engaged, but you'd be wrong. And that's a good thing.
Where else you've seen him:
"Studio 60 on the Sunset Strip" and "Arrested Development"
