If you’ve ever wanted to own a hornet jock strap that was once worn by Zac Efron, then your interesting dream has come true as costumes from the film Dirty Grandpa are now up for auction.

The bidding for 100 authentic props and costumes from Efron and Robert De Niro’s raunchy comedy began on Monday, with the online auction open until Friday, June 10. Other highlights from the auction include a horse head mask that Jason Mantzoukas sported, some snazzy Efron suits, a few Hawaiian shirts that De Niro wore, and a bathing suit/overalls combo that was donned by Aubrey Plaza.

The listing for the jock strap states that it “shows assorted stains from use during production but remains in good condition.” As of Tuesday afternoon, it has the highest bid of any of the items in the auction at $50. 

To see all the available Dirty Grandpa props and costumes, browse through the auction at Prop Store.
