Cut their tongue out (Saint Paisios the Athonite)

Because they know in advance the great effort required for the journey, the big birds that migrate to warmer countries show great love and bear on their wings any smaller ones they come across. But they’re often verbally attacked by chickens whose eyes are puffy from all the filth they scratch around in every day, to the extent that they can’t see straight, the poor things. It would be in such people’s best interests to take a pair of scissors to their tongues rather than go to Hell, since they find it so hard to keep their mouths zipped.
