Good Friday

If you are a good Christian, you will have eaten fish yesterday - or at the very least, you will not have eaten meat.  Why not?  Because Good Friday is a fasting day, and meat is forbidden.  Strangely the Church has never considered fish as meat and so it can be eaten.  Many people expand this idea and always eat fish on Fridays.  Why do we call it Good Friday when it commemorates the Crucifixion which would hardly be considered a good thing.  Nobody seem to know for sure, although it has been suggested that it started out as God's Friday.
