You have to understand Jesus. He was all alone the day we took that photo. Jesus has since found a mate, Helga.

His name came about when a college student who was studying religion told me that it would be sacrilege to call a sheep Jesus. So I went, got myself another sheep (the ones we had already were named at this point) and called it Jesus.

The point being an allusion to the Psalm reading "Jesus, Lamb Of God". Obviously.
