When the milkman found a note on one of his customer'sdoors asking for 16 gallons instead of the usual quart,

he rang the bell."Sorry to bother you, ma'am," he said, "but are you sureyou want sixteen gallons of milk today?"

"Oh, yes," said the lady of the house. "I'm going to takea milk bath."

"Do you want it pasteurized?"

"No, just up to my tits would be fine."
