Happy Mad Scientist. This costume is almost completely homemade. I took an old sheet and made his lab coat from that. Took a piece of old material and constructed a bowtie. I borrowed the black rimmed glasses from a friend and put a piece of paper towel, covered by clear tape, in the middle b/c I had no white tape. I made a pocket protector out of construction paper and covered it with contact paper to give it a plastic look. Topped it off with some goggles, a preppy outfit, some Converse, and some seriously teased out hair.
