"Is Nudist On The Checklist?" joke

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!"
