Do this one. (If your spouse is a bit squeamish, then best accomplish this without them being in the kitchen) Catch a live toad. Fill a large pan with cool water and place the pan on the stove. Put the toad in the pan and then turn the burner on to low heat. The innocent soon-to-be-in-danger toad will sit contentedly in that water, never dreaming that his nice, personal paradise will begin to heat up and his lovely new home will steadily turn into a personal pit of death. He will sit there enjoying his little pond, not recognizing that is getting warmer, then entirely too warm, and then eventually will cook him to death.
