Yes, another strip that I did the 'research' thing on...it's always a good way to come up with inspiration. Most dictionaries will have enough information to do a gag on, and Easter was no different. The Irish taking the cake? That begs to be parodied.
As far as beliefs go, why is believing the earth to be hatched from a giant hen so unbelievable? Besides Scientific Proof, that is...you've got to suspend your common sense to get behind some of the crazy ideas that people believe. Finally though, the greeting wishes in the last panel relay the real message in the strip, enjoy life!
