Caddyshack premiered 35 summers ago, produced with a budget of $6 million. The film made more than $39 million at the box office, and its cult stature has made it even more in the three and a half decades since.

This week, Caddyshack is giving back -- in donations, not strokes. On Friday at the PGA Championship, caddies were spotted with Caddyshack-themed socks, wearing both images of Rodney Dangerfield's character, Al Czervik ("Call Time"), and the Bushwood Country Club gopher ("Aftermath").

The socks are made by the sock company Stance in partnership with St. Jude Children's Research Hospital and the Association of Professional Tour Caddies (APTC). Caddies at the PGA Championship started wearing the socks, part of Stance's Golf Casual Collection, on Thursday, and they will wear the socks throughout the weekend.

The same two styles are also available on Stance's online store, where 20 percent of each purchased will be donated to St. Jude Children's Research Hospital. The socks are $16 per pair and the promotion runs through Aug. 20.

"We are really happy to support such a great cause, and love that we are doing it in such a creative way with the APTC," said Clarke Miyasaki, EVP of Business Development at Stance, in a press release.

"The members of the APTC are proud to be taking a Stance with St. Jude against childhood cancer and other life-threatening diseases," added the APTC Board.

Much to the chagrin of Carl Spackler (Bill Murray), that gopher is still alive. Now, he is just on socks.
