Every time someone hammers a nail firmly a million suburbanites flood the forums with “I HEARD GUNSHOTS! ANYONE ELSE HEAR GUNSHOTS? TERRORIST INCIDENT?”
Still deciding between that and “WHAT IS THE HELICOPTER DOING LANDING ON TOP OF THE HOSPITAL?” as my favorite genre of cracker neighborpost
I check Nextdoor every now and then just for a laugh. It's usually old people saying stuff like "has anyone else seen this suspicious black man waiting at the bus stop looking like he's going to do something" or "I have a puzzle of princess Diana for sale. £15. Missing 23 pieces"
Grotesque parts of Discworld are all based on reality.
