My folks got rid of their 27 inch TV set recently because the red electron gun inside the tube crapped out, turning everything on the screen a shade of purple. Had I thought of it at the time, I would have had Dad and I shoot a couple rounds into the tube before rolling it down the landfill hill.
I executed an old cathode ray computer monitor and the CPU before hauling them away to the landfill in Helena. Put a .40 FMJ through each. Never did like that computer much.
