Still a virgin
"Father, how am I going to tell my husband that I am still a virgin?"
"My child, you have been a married woman for many years. You have had three husbands! Surely that cannot be."
"Well, father, my first husband was a psychologist, and all he wanted to do was talk, and the next one was in construction and he always said he'd get to it tomorrow. The last one was a gynecologist and all he did was look. But this time, father, I'm marrying a lawyer and I'm sure I'm going to get screwed."
