Christians have a perfectly rational explanation as to how the koalas, which will not eat anything but FRESH (within 3 days) eucalyptus leaves, survived for a year on Noah's ark, and then migrated from Mount Ararat to Australia, even though they can't swim, and left no koala colonies in any of the territory in between.

I don't think that koalas HAVE a religion.

I'm sure there is something in Scientology about shaving them on Saturdays or something.

Pastafarianism. We give those little guys ramen, and they love it.
