Mabel, who is 60 years old, goes to her doctor for her annual physical. He examines her thoroughly and says "Mabel, i've got good news and bad news for you."
Mabel said "What's the good news?"
The doctor says "You are in wonderful shape. I can't find anything at all wrong with you."
Mabel then asked "What's the bad news?"
The doctor said "You're pregnant!" Mabel flew out of his office. She was very upset, and ran home and called her husband at work. When he answered, she said "You old goat-you got me pregnant!"
After a long pause, he said "Who's calling?" ~
