for the greatest number of charity performances made by a show-business performer. Unlike the high-profile shows done by Bob Hope to entertain the troops, Berle did more shows, over a period of 50 years, on a lower-profile basis. Berle received an award for entertaining at stateside military bases in World War I as a child performer, in addition to traveling to foreign bases during World War II and the Vietnam War. The first charity telethon (for the Damon Runyon Cancer Research Foundation) was hosted by Berle in 1949. A permanent fixture at charity benefits in the Hollywood area, he was instrumental in raising millions for charitable causes. Late career On April 14, 1979, Berle guest-hosted NBC's Saturday Night Live. Berle's long reputation for taking control of an entire television production—whether invited to do so or not—was a cause of stress on the set. In addition, he appeared skeptical about the show's satirical bent.

Milton Berle also made a cameo appearance in The Muppet Movie as a used car dealer, taking Fozzie Bear's 1951 Studebaker in trade for a station wagon. In 1974, Berle had a minor altercation with a younger actor/comedian Richard Pryor when both appeared as guests on The Mike Douglas Show. At the time, Berle was discussing the emotional fallout from an experience he had with impregnating a woman with whom he was not married, having to then decide whether or not they would keep the child. During his talk, Pryor let out a laugh, to which Berle took exception and
