A lad from Berlin (mostly Lutheran natives) is in a summer camp run by nuns. All day the children are told religious stories.
When the subject was changed to biology, the children were asked: "What is this? It is small, furry, has a bushy tail and jumps from tree to tree?"
The lad answered: "Well, normally I would say, a squirrel, but knowing the shop here it must be Holy Child Jesus".
(Old German joke, told for decades)
