You cannot use the words "testicles" and "penis" when talking to my son and not expect him to erupt into uncontrollable laughter. He is after all, twelve years old. It just isn't realistic! Anyway, that was nothing. You should have seen him AFTER you left the room!
Judge us as you may... those are just not words we use very frequently in our home... (though I must say, they have been used much more frequently since our trip in to see you!)
