Casey Sander (Mike Rostenkowski)
Mike Rostenkowski’s mustache is all you need to see to tell that he’s a seasoned police officer, now retired. Mike would eventually become Howard’s father-in-law, and the two didn’t have the best relationship ever.
The former cop had strong opinions and voiced them whether anyone asked him to or not. He wasn’t the most communicative person, and many subjects were clearly off the table (gardeners, foreigners, Sean Penn, and organic food, just to name a few). However, that didn’t stop Howard from trying to build a rapport with his father-in-law for the four seasons Mike appeared on screen.
