Canadian sprinter Ben Johnson celebrates Olympic gold in the 100 meters, a medal that would later be taken away because of a positive steroids test.

It was a sad day for Canadian sports in 2006 when Ben Johnson, the disgraced Olympic sprinter, announced he'd appear in a series of commercials for a new sports drink that would poke fun at his past steroid use. The sprinter was famously stripped of his 100-metre gold following a positive test for a banned substance at the 1988 Seoul Games, and - after a two-year ban from the sport - was outlawed for good when he failed a second drug test in 1993. Johnson lost some $18 million in endorsements at the time, but finally made it back to the commercial world to endorse the Cheetah energy drink. The ads were designed to lightly parody the track star's infamous history. In a mock interview, the brand's CEO asks Johnson, "Ben, when you run, do you Cheetah?" The sprinter, rehashing the shame of an entire nation, responds, "Absolutely. I Cheetah all the time."
