Hard to encourage people to give blood when you're not willing to do it yourself. That's the story of two Iranian officials, after journalists released footage of them making fake donations.

The director and an employee of a blood transfusion centre in Yazd, central Iran, decided to get local film crews to document them giving blood as a way of getting others to do the same. They didn't actually want to give up any blood however. But the result, seen in this video, probably got them more attention in any case.
