Kindergarten.Snack-time.Children quietly convey Chex mix softly rattling across paper plates to their desks.And the one with a wooden chair on her head, a cup half-filled with orange juice balanced on the seat, dancing the Steve Martin “wild and crazy guys” shimmy?That’d be me.Minutes before, I’d told some joke the other kids laughed at.It was all the encouragement I needed to spring my inner funny on them full tilt, let loose and be the me I was at home, the me who invented the make-the-corpse-laugh game and kept a rubber-worm fishing lure in a box with holes cut in it.What could be funnier than that?Except maybe a five-year-old shimmying with a chair on her head balancing a cup of orange juice.
