In the modern cinematic masterpiece Dirty Grandpa, Zac Efron’s hunky character gets drugged by his grandpa (Academy Award–winning actor Robert De Niro), smokes meth, and wakes up on a beach in a hornet jockstrap. (It happens.) You can now buy this jockstrap, which measures 11.5†x 6.5†x 5.5â€. The asking price is $70, but it’s probably worth much more — it literally hung from Zac Efron’s loins. It “shows assorted stains from use during production but remains in good condition,†which is promising.
