Showbiz vet Jerry Lewis says he has ZERO tolerance for young celebrities like Lindsay Lohan and Paris Hilton who seem to f**k up with no conscience.

The 84-year-old comedian recently spoke with Inside Edition and said that he wants to smack Lindsay Lohan in the mouth….and if that doesn’t work, he wants to “put her over my knee and spank her” before sending her off to rehab for a while. Why? Because he feels as though she’s the prime example of a young star taking everything for granted.

“I’d smack her in the mouth if I saw her. I would smack her in the mouth and be arrested for abusing a woman! I would say, ‘You deserve this and nothing else…’ Whack! And then, if she’s not satisfied, I’d put her over my knee and spank her and then put her in rehab and that’s it. She doesn’t have the right to do to herself what she’s doing. She’s not hurting my business. What she’s doing is hurting herself, and that hurts me. It hurts me for her.”

And Lewis didn’t stop there. He also had a few words for another royal f**k up …. Paris Hilton, who was just arrested last week for felony cocaine possession!

“What they’re (Hilton and Lohan) saying is, ‘I’m f**ked up, can you please help me! I think they need a f**king spanking! And a reprimand…! They have the intelligence of a box of rocks. A bag of snails will give you better answers than those people. I think a great deal of it is ignorance and crying for something other than love.”

You tell ’em Jerry! Can we help???
