Mike Rostenkowski is the father of Bernadette Rostenkowski, Joey Rostenkowski and four other children, husband of Mrs. Rostenkowski and the father-in-law of Howard Wolowitz. His first appearance was in "The Launch Acceleration." He is a retired police officer and is portrayed by actor Casey Sander.
Before he was first seen, Bernadette warned Howard not to mention Jimmy Carter, gardeners, foreigners, homosexuals, Sean Penn, Vatican II, organic food, designated hitter rule, gun control, recycling, or Howard's Jewish heritage, indicating that he is far-right-wing.
Overall, Mike is a hardened and retired police officer, who has a rough and rude personality, and often bullies others. He admitted to Howard that he does not like him, but is impressed with him being an astronaut. He appears to have a soft spot for Bernadette, calling her his "little girl." He has called Howard's mother a "piece of work" and pointed out that she had an even bigger mustache than him. He mentioned that his former partner was shot and killed by his partner's insane wife.
He doesn't seem to care about Howard at first, but that later grew after Howard became an astronaut and married his daughter.. When Howard told him of his terror of going to space, Mr. Rostenkowski said "It's gonna be okay, son. A pretty girl like Bernadette... She'll find a new guy."
He appears to be incredibly strong, since he was seen cracking walnuts with his bare hands in "The Launch Acceleration."
In "The Fish Guts Displacement," Howard and Bernadette are having dinner with her parents. Howard and Mike get pushed into a fishing weekend by their spouses and it turns out neither of them want to go. Mike suggests that they go to a casino to shoot craps. They bond somewhat and he tells Howard to call him Mike and no longer "Sir". In this episode, he reveals that he likes to use big shells while duck hunting so that they explode: " you can't eat them afterwards, but it's fun watching them blow up."
In "The Thanksgiving Decoupling," his wife is out of town and Bernadette gets him to come to Howard's mother's house for Thanksgiving dinner though he would rather watch football at home. Since Sheldon knew football thanks to his father and had lost his father, Mike and Sheldon bond and get drunk together.
In "The Table Polarization," he, Bernadette, Raj and Mike Massimino (via web chat) perform an intervention on Howard's decision to go back to space (Mike had to be prodded by Bernadette to agree about loving him). He mentioned that Howard asked him to shoot him in the foot, at which Howard insisted was a joke. Mike, along with everyone else except Bernadette, laughed when Raj brought up Howard throwing up in zero gravity and his vomit went right back into his mouth, a cycle which repeated constantly.
In "The Spock Resonance", Mike is brought to the Wolowitz House by Bernadette to start construction when she wants to start redecorating. A very funny scene with Mike and Howard happens under the house - Mike wants to know why Howard doesn't want kids. Howard denies that. Bernadette hears their conversation under the floor and starts trying to make an earthquake and aftershocks so that they'll stop talking. Last scene with them reveals that his wife raised the kids while all he did was come home from work, sit on he couch and drink beer and also Howard and Bernadette's conversation after Mike leaves sounds like they are seriously considering a baby.
He and his wife were both mentioned by Bernadette in "The Escape Hatch Identification" when it's revealed that they were looking after Halley for a while.
