From Dalton Trumbo's Johnny Got His Gun:

"She (his mother) had a marker in the Bible and she opened it now to the place that was marked and began to read again. She read the story of the Christ-child of the baby Jesus and how he was born in a manger...All the people were going to Bethlehem because it was tax time and they had to appear at the court house and register and pay up...Joseph had to do a lot of chores before he could start out and Mary his wife was pregnant and couldn't help him so they were late...As soon as they got into town Joseph began making the rounds of cheap rooming houses. He wasn't much of a success at making money and they only had enough to pay taxes and one night's rent...Then Joseph began to talk very seriously to the hotel manager. See here he said I've come a long way and I've got my wife with me and she's going to have a baby. Look at her out there on the donkey, you see she's just a kid and she's scared...(Hotel manager talking)It'll be an awful mess if she has a baby on the premises, people who can't afford them shouldn't have babies anyway but what are you going to do about it...I don't mind telling you I hope very much she doesn't have the baby here tonight because it'll upset my guests if she screams and they're all very high class people including three Roman congressmen...Oh I almost forgot, don't light any fires out there in the barn because in my insurance it says they're forbidden...Back in the manger Joseph lighted a lantern and fixed up a nice bed on the hay and Mary lay down on the bed and had her baby...
