My brother and his family purchased some baby chicks around Easter. One of the kids left the garage door open and an animal got in and killed all but one of the chicks. This chick's name was "Pecker". Because she survived the attack, the kids decided to rename the poor chick "Lucky Pecker." I'm not sure how my sister-in-law managed to miss the hilarity of the name, but she didn't catch on until she heard someone snickering about it at church when she was talking about the chickens.
At least all the new chicks have normal names.
My husband and I will sometimes take turns saying "Lucky Pecker" just to get the other person to laugh.
