Sensors have to be stuck to me and though I am balding I have hair front and back from the neck down. That meant a shave back on the chest and the back of the head for electrodes to be fixed. It's not the first time I've shaved for medical purposes. Only this time it won't be a wasted fail. I once got my stomach waxed for surgery instead of shaving but got the wrong spot done so they shaved anyway; all that was left was the top left quarter—I looked like an Oz flag with a clear one-nippled pink sky with hair and other nip replacing the Union Jack. Also, when my stomach was waxed, this happened. I'm about as hairy as Carrell save for my projecting sides. It hurt as much as it did for him in that scene. Like bite through the brim of your hat bad. Then the blood seeps up ... it's just yucky. Who bought this up? Wrong.
