It’s not a conventional display of brotherly love, but getting tattooed during a bumpy roller-coaster ride demonstrated the unwavering trust between two modern-day B.C. daredevils this week.

Brothers Burnaby Q. Orbax and Sweet Pepper Klopek, who together make up the touring entertainment duo Monsters of Schlock, achieved what they describe as their “stupidest” stunt on Wednesday.

Orbax etched a tattoo on his brother’s leg while the two rode Canada’s oldest-running wooden roller-coaster at Vancouver’s Pacific National Exhibition.

“We’ve done much more dangerous stunts all over the world, but this is probably our stupidest stunt that we’ve ever done today,” Orbax told reporters.

Self-described as a “professional, freak-show, stunt-show daredevil team,” the brothers perform throughout Canada and have been featured in ‘Ripley’s Believe it or Not!’ 

Their latest stunt is believed to have been the first time someone was tattooed on a moving roller-coaster.

Two full trips on the ride were needed for Orbax to complete his masterpiece -- a stick figure with a smiley face.

In fact, Orbax said it was the first time he had ever tattooed someone.

The Monsters of Schlock are currently performing during the PNE’s Fright Nights, which run until Oct. 31.
