Want a jock strap like the one Zac Efron wore in "Dirty Grandpa?" You're in luck.

Zac and Robert DeNiro teamed up for the movie, which filmed in metro Atlanta and on Tybee Island. Released in January, it's about a straight-laced guy who takes his lascivious gramps to Spring Break right after his grandmother's funeral. Now a company is auctioning off assorted props and gear, including this particularly intimate garment.

The auction company, called Prop Store, has this fine piece of cinematic history on the block along with tons of other stuff, in case you're interested in the argyle sweater Zac wore or DeNiro's Hawaiian shirt.

The hornet codpiece is leading the pack in terms of bid price ($50 as of this moment). It's billed as a "stunt" piece indicating Zac's body double wore it. He's no doubt had the original bronzed. Wouldn't you?

Details:

"Jason Kelly's (Zac's character) stunt stuffed hornet jock strap from Dan Mazer's comedy Dirty Grandpa. After being drugged by his grandpa and accidentally smoking meth, Jason ends up in a stuffed hornet jock strap dancing and later wakes up on the beach wearing it. This stuffed hornet undergarment is made of a stuffed cotton blend hornet lined with a nylon cup piece and worn with thin urethane clear straps. The hornet  features wired antennae that can be bent into place. A wardrobe tag reading "Stunt Jason w/ Hornet" is included. The item shows assorted stains from use during production but remains in good condition. Dimensions: 11½" x 6½" x 5½" (29 cm x 16.5 cm x 14 cm)"

Next to the Rosebud sled from "Citizen Kane" we can't think of a more significant piece of movie memorabilia! Bid early and often here.
