The best put-down line ever....

I love humorous put-down lines.  You know, the ones that just cut someone to shreds, especially if for whatever reason they deserve to be put down -- rude, whatever.  I don't mean maliciously or in an immoral fashion, butt in good fun!

Because I love to hear this type of humor, put-downs, I want to hear from all of you the best lines you've ever said, heard, or for that matter been on the receiving end.  

I'll kick it off.  A few years ago, my mother and stepfather were visiting us, and we love to discuss various subjects.  Among other things, that particular day the subject turned to abortion.  I asked my mother, who had me at only age 22, if she ever had considered having an abortion with me.  She replied, with an uncomfortably short pause in time, "Yes, sweetheart.  But, it was fifteen years too late."

I thought my wife and stepfather were going to fall off the sofa, they were laughing so hard.  I of course, knowing full well that I was whipped, said nothing.  In baseball vernacular, I walked back to the dugout, bat on my shoulder, and hung my head.   She was and still is hilarious!
