2.
One who attends church exactly twice per year, on Easter and Christmas, resulting in overcrowding. Necessitates regular churchgoers to arrive 45 minutes earlier than normal in order to find a parking space and a seat.
Wife: Honey, get the kids ready for church.
Husband: But it's forty five minutes early.
Wife: I know. It's Easter. If we don't leave now, the creasters will get all the good seats.
