NNB, you know what happens.
If I tried to do anything with a warming toilet seat, you’d get:
a) A toilet seat that makes am omelette out of one’s backside.
b) A toilet seat that gains sentience and then rampages.
c) A toilet seat that suddenly decides to become a carnivore.
Maybe all of the above, maybe not in that particular order.
(Be afraid. Be very afraid.)
