In our case... it absolutely is the case. Every day in some way or another, there is a voice in the back of my head asking "Really???".
We recently got a couple of kittens, and wound up putting the litter box in our downstairs bathroom, in the under-sink cabinet, leaving the door on that side open. DS5 decided he didn't like the litter box smell, so without mentioning anything to us he "solved" the problem by drenching the entire bathroom in two bottles of Febreze. It was dripping off some stuff. My wife said something like, "So
this is what it means to be ultra-bright, hmmm?"
