One of the best costumes my folks ever made for my brother was "the mad scientist." It consisted of a lab coat, an Einstein-style wig, a black moustache, pipe, and granny glasses. In the pockets of the coat Dad had placed severed fingers, a tube of fake blood, and a stethoscope. The bag Al carried was covered in mathematical formulae — a real nod to Dadâ€™s ability to do research. I donâ€™t recall what I wore that year, so…Al was a hit and I was a miss.
