It can regularly spoil a joke to need to explain it. In this case the Monsignor [Failblog FAILS! in calling him a “cardinal” – this is clearly NOT a cardinal] confuses the microphone that he has just been speaking into with the aspergillum (seen 0:20), a similarly shaped object used for sprinkling with Holy Water.
These things obviously catch a few people out; there’s another video in which a woman at a wedding is handed the mike, so as to say a few words, and she starts using it as the pepper shaker….
Well, he broke a cardinal rule of electronics, so he must be a Cardinal!
