You know every time I see mister_e's picture (the head bang'n on the desk gif) -- reminds me of a case I studied for my assignment on capital punishment. In the states a few years back they executed this guy in the gas chamber (I think he was a pedophile) -- took over 10 minutes for him to pass out, he spent most of those 10 minutes banging his head on a pole (this is the part that reminds me of mister_e)
