My son got his cast removed today. I came home to see it on our kitchen table with no son attached to it. He was upstairs taking a shower and getting the "Smelly Arm" cleaned. The cast was cut in half and someone at the Dr's office must have taped it back together for him (I am sure the tape occupies a line item on the bill too). I was thinking of putting my flash inside the cast and have it firing out, however, this cast is tiny. There is no way I can get my 580EX-2 inside of it.
