Speech Impediment
Over drinks one afternoon a buddy of mine and I were discussing former "loves". I told him that I once broke-up with a girl long ago because she had a seemingly incurable speech impediment.George said, "Jimmy, I'm shocked. I never know you to be one to be prejudiced against handicaps. What was the girl's problem?"
Taking a sip, I paused and reflected. "She couldn't say 'yes'."
