The "pull my finger" prank has been a staple of Dadisms since dads were invented. It's one of the earliest pranks a dad pulls on his kids, along with the snipe hunt and finding the barking spider under the couch.
The general idea is that a dad tells his kid to pull on his finger. When the innocent child does as they are asked, the dad lets rip a loud and pungeant fart. Of course, there must be a dad somewhere that was pulling this prank at the exact moment that the Northridge Earthquake started, traumatizing the child and giving a psychotherapist a lifelong patient.
I cannot confirm nor deny that I pulled this prank on my kids.
