He played the deadbeat brother-in-law on the sitcom "Yes, Dear" from 2000-2006.
I probably have seen every episode of that show (don't Blaime me, my kid loved the show, but it wasn't horrible).
Over the entire series I NEVER saw him without a hat on, and it was clear he was sly. Even at the Emmy's he wore a Fedora or Barrett. I recently found out why, he has a MAJOR dent in his crown, almost looks like he might have had brain surgery as a child. Has anyone seen him? You can Google him but I doubt you will see him without a hat. I have always said I think almost EVERYBODY looks good sly, not in Mike's case.
Yes, I've seen him. True, he does usually wear hats, but I never knew why. I have seen only a couple pics of him without a hat.
If you Google him, there are a couple pics of him hatless, but they are from a distance and dead straight on his face so you can't really see his dome...
My family used to watch Glee and he is smooth in lots of those episodes with no hat and I haven't ever really noticed anything out of the ordinary
