Better Half

One time, a friend told me that he was going to have to check with his better half before making plans for Saturday night.  I told him that I had never realized that he was also a twin.  I also told him that my twin - Kram Sheldon - was the Evil one and I was the Good one, and that Kram never bothers to check with me first before making plans.  Some Evil twins just have no respect for their better halves.
