Don’t ever ask Larry David about his net worth.

The Seinfield co-creator appeared to be both serious and joking when he said it was none of his business.

In the latest episode of Who’s Talking to Chris Wallace? on Max, the 76-year-old veteran newsman recalled to David that his father – the famed 60 minutes correspondent Mike Wallace – once told Johnny Carson that people are always “fascinated” by how much rich people are worth.

David did not even allow Wallace to finish the question, as he intercepted him saying, “That’s terrible. Terrible question” with spot-on timing.

He added, “Who’s your father think he was, by the way?”

Wallace insisted it was great question, which is why he then proceeded to ask it, much to David’s chagrin.

Wallace tell David that internet suggests that it is near half a billion dollars, which made David spit out the water he sipped.

In an attempt to avoid the question, the Seinfield co-star stated that he does not have any more water. But Wallace doubled down asking him the question again.

“I’m gonna say what should have been said to your father — none of your f–king business. How about that?” replied David, before scoffing at the “half a billion dollars” estimation regarding his net worth.
