Bill Murray has paid an idiosyncratic tribute to Harold Ramis. The comedy pair worked together several times, most famously appearing together in Ghostbusters.
Murray told Time Magazine:
Harold Ramis and I together did the National Lampoon Show off Broadway, Meatballs, Stripes, Caddyshack, Ghostbusters and Groundhog Day. He earned his keep on this planet. God bless him.
