You say dumb, I say forgetful.good grief, you guys are dumb LMAO!!!!!! If you do something enough times it becomes muscle memory and you naturally unplug things BEFORE starting the WC haha Besides, heaters are supposed to be unplugged 15 minutes before taking them in or out of water so they can be at room temperature. I don't mean to be a douche, but I can't help but laugh at this stuff - that's not being very smart or aware.
