The census taker rang the doorbell and was quite surprised when the door was opened by a nude woman.
"Don't be alarmed," she said, "I'm a nudist."
Although somewhat embarrassed, the man proceeded to ask the routine questions.... "How many children do you have?" he asked.
"Eighteen." The lady replied.
"Lady," he gasped, "you're not a nudist - you just don't have time to get dressed!"
