Paddy O' Leary had spent the eve drinking at the local tavern. He knew he had a long walk home, so though he was a wee tipsy, he recalled a shortcut through the town's cemetery.
Paddy staggered 'round the graves, but lost his footing and fell into a hole dug for a burial the following day. He passed out when he hit bottom.
Upon awakening the next morn, Paddy stood up and realized where he was-- and promptly shouted "Glory Be to GOD! 'Tis the Resurrection Day-- and I'm the first one up!"
