Colin MacDuff never said no to a challenge. That's why he was currently standing on his head, sucking down a two-liter bottle of Irn Bru through a jumbo pink curly straw.
There were other motivations, of course.
Truth, for instance - busting the myth that one could get hammered by guzzling "Scotland's other national drink" whilst upside down.
Or curiosity - how would it feel to consume suck a massive amount of sugar, caffeine, and orange food coloring at once?
Or even simple economics - hey, free Irn Bru!
But mostly he did it because his mates dared him. He had a reputation to uphold, after all.
