Newman mail never stops

A classic reference!

"Newman" is a character from the TV show "Seinfeld", played by Wayne Knight. He's a mailman who is constantly frustrated by the incompetence and laziness of Jerry Seinfeld and his friends.

The phrase "Newman mail never stops" is a humorous way of saying that Newman is always delivering mail, no matter what. It's a running joke throughout the series, with Newman often showing up at Jerry's apartment or other locations, always with a package or letter in hand.

The phrase has since become a popular meme and cultural reference, often used to describe situations where someone is always showing up or delivering something, no matter how inconvenient it may be.
