What is the most intelligent one liner you have come across?

I was at a dance with some pals, we were all in our late teens and I spotted a really attractive blond, so I told my pals that I was going to ask her for a dance. They all laughed, she must have been in her early twenties and they said she wouldn���t even talk to me. So, I went over to where she was sitting and asked if she would like the next dance. She looked at me, looked at her friends and said (rudely) ���Sorry, but I���m not going to dance with a baby.��� I thought for a moment, and replied ���I do apologize, I didn���t realize you were pregnant.���
