How many btu's do witches have? Plus I imagine the neighbor's would complain about the smell of that. Nothing's worse than an OWB, = Outdoor Witch Burner.
It really depends what kind of wood they are made of... figure that out and you know the BTU content...
Being from an old New England family where we used to burn witches for sport, it was estimated that a human has about 25,000 BTU's (true), which is about a bundle of firewood...wet. It was not the smell that was obnoxious, but their whining as they were being burned. Sissies! That got kind of old, so my family decided Taring and Feathering was better. It gave us something to do with the plucked chicken feathers we had kicking around, and who does not like boiling up hot asphalt to dump on a person so they stick well enough? I just read this reply to Katie, and she said that she was "so proud at being married to me." I am not certain on whether or not she was being sarcastic. Probably the latter. Actually...and this is true, no Witches were burned at the Salem Witch Trials. The first guy was stoned, but it took him 3 days to die, so they hung the rest. In that time period, my family endured 3 that went on trial. One was convicted and hung. One was convicted, but the sentence never carried out. And a third was acquitted. They claim the people were getting hallucinating from gathered mushrooms found in the forest. Oh how times have changed. In the 1600's a person was hung for having 'shrooms! Now the police catch a person high on 'shrooms and laugh it off, and fine them heavily for not wearing their seat belts instead.
