Bill Murray
Bill Murray was actually a caddy before he hit the silver screen. He carried golf clubs at a local golf course while he was studying at Regis College when he wasn't singing in his band. After Murray graduated, he was invited to join a comedy club by his brother. By the 1970s, Murray landed a spot on Saturday Night Live. He then starred in the movie Meatballs, which led to him staring in Scrooged, Ghostbusters, and Caddyshack.
