Newman: Mother’s Day. The mother of all mail days.

Who is Newman?

Newman (Wayne Knight) is Jerry’s sworn enemy, chief collaborator in Kramer’s schemes, and the finest villain the U.S. Postal Service ever produced — ranked among TV’s all-time greats by both TV Guide and Rolling Stone. No first name ever given. Greeted with “Hello, Newman” through gritted teeth; returns “Hello, Jerry” with false warmth. Pure evil, per Jerry, on multiple occasions.
