I once knew a family who had a poodle that loved to sniff its own farts. Audible or not, once the fart was emitted, the dog’s nose would immediately gravitate toward its butt. Naturally hilarity would always ensue. To up the ante, now and then a family member or friend would make a fart noise just to watch in amusement as the dog would, in response, yet again sniff its own butt.
That is some cheap entertainment, in which everyone wins.
