CATHOLIC CHURCH: No meat on Fridays
PEOPLE: Ok so no eggs for breakfast
CC: No, eggs are ok
P: But eggs are chicken
CC: Not until they hatch
P: So the thing isn't the thing until it's born?
CC: Correct—um, no, wait.
@juglugs By the way: the Catholic Church is more progressive than most Christian churches in the USA.
I understand the joke, but it would be better to use some typical protestant church in the US.
