A group of BASE jumpers from Poland have found success in reaching the tops of guarded buildings while wearing a specific disguise—they dress as priests. The extreme sports team, No Limit, was able to sneak past security thanks to their outfits before leaping from Warsaw’s Palace of Culture and Science.

“Disguised as men of the cloth, the four-man team smuggled their parachutes under their cassocks—hidden between their legs—past the building’s strict security,” the video’s description reads. “As passers-by watched in amazement, the phony fathers then climbed out onto the ledge and leaped from the building, landing safely in the car park below.”
