Mrs Rostenkowski

Mrs. Rostenkowski is the mother of Bernadette Rostenkowski, who is said to be just as motherly over Bernadette as Howard's mother is over him.

When Berndatte and Howard were discussing their mothers, Bernadette mentions a few things of her mother that drives her crazy:
 * Calling her at work to find out if she's had a healthy lunch.
 * She lays out Bernadette's clothes for her, while not even living with her in the same house.
 * Bernadette couldn't ride a bike when she was younger, as Mrs. Rostenkowski was afraid she would "hit a bump and lose her virginity".
