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.
