Lady of the House, "Mildred, are you putting on weight?"
Maid, "Well, to tell you the truth Madam, I am pregnant." Lady, "OH DEAR! How ever did you get your self in such condition?"
Maid, "Well Madam it started when I ordered a vibrator through the mail."
Lady, "Goodness! You didn't use that dreadful thing did you?"
Maid, "No Madam, the mail man talked me out of it."
