When it came time for the Catholics to try and convert the pagans, to Catholicism, they heard a story about a pagan priestess named Esther, who was famus for having transformed a swan into a rabbit but the rabbit cold still lay eggs, eggs are in the shape of an oval which is the pagan symbol for fertility and rebirth. The Catholics embedded this story in with the rebirth of Christ and bam we all got an Easter (Esther) and an Easter Bunny..so wake and bake have some sex and celebrate fertility and rebirth (just be careful not to end up with an actual birth unless you want to)
