Durex agency Fitzgerald+CO conceived the viral, which was produced by Superfad New York.
Robert Rugan, creative director at Superfad, said: "When you get the chance to create 'karma-balloon-animal-sutra', everyone involved gets really stoked about pushing the boundaries as much as possible.
"Not only did the agency give us the opportunity to do that; they encouraged it. Oh, and the conference calls were some of the funniest I've ever been on."
