For 6 years running I designed elaborate costumes and with the help of my then wife constructed.
I was:
1. A slice of toast with pat of drippipng butter on it
2. A divot with a tee stuck to it
3. A Fudge-cicle
4. First Base, I wore an L.A. Dodgers hat
5. A cutting room floor
6. A vibrator
#1,2,3,4 & 6 were all either 4-5' wide or tall and typically covered my whole torso. In the case of the Fudge-cicle it came up about foot over my head and my face stuck out of it. My pats were "white" as that was the stick and they had drips of brown felt in the shape of ice cream drips.
The cutting room floor was the simplest as it was just a bunck of VCR, cassette, 35mm film attached to my white clothes. Each had a tag attached to what it was. One was the deleted 5 minutes of "Truckin'" by the Grateful Dead. Another was the film of Marily Monreo singing Happy Birthday to JFK (in his private dressing room before the event).
The vibrator better well be explanatory. I completely covered me from head to knees and I made a screen so I could sees out but it was difficult for any one to see me. It had a button on the front that triggered a buzzer. When people pressed it I jiggled.
