I used to have a special Xmas one that went
"Hello.You have reached the Bethlehem Motel and Diner.I'm sorry there is no one to take your call but we are having a small emergency out the back in the cow shed.If you are calling for a reservation, I'm afraid there is actually no room at this inn.If you are calling to complain about the light from yonder star,it is not, repeat not,anything to do with us even though it happens to be above the Motel.If you are calling to complain about the livestock/lack of available shepherds/royalty making off with your myrhh,we can only apologise.We expect normal service to be resumed as soon as possible."

It made the children laugh anyway.*BG*
