"Big Bang Theory" Spanking

I don't know about Leonard's mother not being up to the task, she used to spank Leonard's father with a ping pong bat.

That's true, but that was when she was trying to save her marriage. And she made it clear that she wasn't into it anyway. She never seemed to have spanked Leonard or, presumably, any of his high-achieving siblings. Maybe if Penny got her drunk enough (and if Penny was drunk enough) and there were no cute busboys around...
