Joe Besser (August 12, 1907-March 1, 1988) was a comedian, known for his impish humor, and is now best remembered for his brief stint as part of the Three Stooges.

He was born in St Louis, the ninth child of Morris and Fanny Besser. He had seven older sisters, and an older brother Manny who was in show business. From a young age, Joe was also fascinated with show business, especially the magic act of Howard Thurston that came annually. For years, he asked Thurston if he could join the act, and Thurston kept telling him to wait until he was older. When he was twelve, Thurston allowed Besser to play a minor audience plant (as in, "stooge"). Besser was so excited by this, he snuck into Thurston's train after the St. Louis run of the show was over, and was discovered the next day sleeping on top of the lion's cage in Detroit.

Thurston gave in, informed Besser's parents of the situation, and trained him as an assistant. The first act involved pulling a rabbit out of a hat. The trick involved two rabbits, one hidden in a pocket of Thurston's cape. But young Besser was so nervous that he botched badly, pulling out the rabbit from the cape at the same time as the other rabbit was on display, before the trick had been performed. The audience roared with laughter, and Besser from then on was assigned comic mishap roles only.

Besser ended up in vaudeville, doing comedy in general, and was a headliner. He specialized in playing a bratty, whiny child. His catchphrases "You crazy you!" and "Not so fast!" became well known.

In 1932, he married the dancer Erna Kay, real name Erna Dora Kretschmer, known as "Ernie". They were neighbors and friends of Lou Costello, of Abbott and Costello fame. He was in demand in movies, radio, and eventually television. One of his most famous roles was "Stinky", the bratty child dressed in an oversized Little Lord Fauntelroy outfit, shorts, and a flat top hat with overhang. He played that for the first season of The Abbott and Costello Show. (In the second season, he was replaced by a chimpanzee.)

When Shemp Howard suddenly died in 1956, Moe Howard recruited Besser to join the Three Stooges. He agreed, but had a clause in his contract prohibiting being hit hard. In 1958, Columbia Pictures ended their "shorts" film making, and the Three Stooges were without a contract. Ernie had had a heart attack, so Besser was unwilling to travel, and he quit the team.

Besser returned to films and television, most notably as the superintendent "Jillson" for four seasons (1962-1966) of The Joey Bishop Show.
