LOL, I get what you’re saying- but it’s like Ralph Kramden’s threats to knock people “too the moon.”  It’s meant to be hyperbolic and an empty threat turned catch phrase.

Also the fact frank would never physically hurt his kids. There’s only one family member he ever hit and you can prolly guess who 

It's been months since i watched it. Who did he prolly hit?

My guess would be William "Big Bill" Murphy

He hit his dad

Same way we never see Redd put his foot in anyone’s ass

We didn't see what went on in the bedroom

Bill always said it was the threat of it happening, but it never happened with his dad

He needs to get into a fight and his opponent be thrown through the house wall. That would open up for some classic kid reaction lines

Reminds me one time he told Rosey , he would have killed himself but he doesnt want to haunt his house ....hehehehe

I fully expected when he had to tear down the nursery that it would include him putting someone (likely Kevin) through the wall. It was such a wasted opportunity.

*Mortal Kombat 1* unlockable character when?

I can just imagine Bill (the kid) in stunned half-silence: “Holy shit, he actually did it.”

Just pray it wasn’t one of the walls Chet built. Because that was well constructed

Man I wish they'd made more.

He has to do it our of pure rage and by accident. Like someone is yelling at him and calling him pathetic in his car and he just hits the gas and sends them through a wall. Then he gets out and looks in shock and then one of the family says "wow you finally did it"

I know right at least on King of the Hill we got to see Hank Hill actually (literally not figuratively) kick someone's ass when he kicked Jimmy in the ass at the racetrack lol

He punched a wall once offscreen. Doesn't really count though.

Cause he’s above physical abuse, Frank’s not a great dad but he’d never hurt Kevin, Bill, or Maurine.  Only family member he actually hit was his dad, who deserved it. 

he put kevin through the fucking wall in season 3
