Just thought this joke was too good.
A lady from a foreign country who could not understand much English wasn't feeling well and went to see her doctor. After examining her he said, "You are pregnant. Please understand that you have an insufficient passage and if you have a baby it will be a miracle."
The lady rushed home crying and told her husband, "The doctor says I'm pregnant and I have a fish in the passage and if I have a baby it will be a mackerel!"
