As humans, we remember the many firsts in our lives...maybe not our first word or first steps, but things like first time riding a bike without training wheels, first date, first kiss, first marriage (whoops how'd that one get in there LOL!)...anyway, you get the idea.
Well have you ever milked a cow? I think I did one time on a field trip back in grade school. This little boy was all ready to try his hand at it, until touching the teat reminds him of a human body part. You may be able to guess which one. His reaction is priceless! And fortunately for us, the encounter was caught on video!
