We had a health fair at work recently and I forgot to wear a good shirt for rolling up a loose sleeve to get my flu shot. One of my coworkers had the misfortune of witnessing me unbutton enough to get a bare arm out out for the needle to the shoulder. I felt the awkward mix of embarrassment and screw-it-I-am-what-I-am-a-hairy-beast pride that I suspect fuels Robin Williams's manic humor. (And perhaps his lust for cocaine.)
