Bill Murray’s representatives have not yet returned CNN’s request for comment.
“William Murray Golf was created on the notion that life and golf don’t have to be so serious. Keep it light, have fun, and bring personality onto the course,” according to the company’s website.
Bill Murray famously played a deranged golf course groundskeeper in the 1980 movie, “Caddyshack,” that was co-written by his brother, Brian.
