I have a friend with a PhD in geology, who is dean of a local college. He has explained to me, on several occasions, 1. Why hot water freezes faster than cold water,and 2. why melting the polar ice would bring on another ice age and 3. why the moon looks huge on the horizon but smaller as it rises. My brain refuses to admit his information. (My brain has also rejected three lobotomies.)

   I went to Ireland a few years ago and rented a car in Dublin. The rental clerk was friendly (just like everybody else in Ireland,)and informed me I had better learn the reverse lane business in about 3 minutes on the streets, or die. I chuckled and said yeah, you guys drive on the wrong side of the road.
    He looked at me for a couple seconds, then said "I'm going to tell you something that will save you a lot of trouble, if you catch onto it. We don't drive on the wrong side, we drive on the other side."
