Two guys who'd made a fortune in the fanny-pack business realized sales had hit the skids because fanny-packs had become tainted as being "un-cool."
"Morty, what are we going to do? If this keeps up, we'll be ruined!"
"Relax Abe, nothing to worry about. We just lengthen the straps and change the name to "Sling Bags"
"Morty, kids aren't that dumb--they'll never fall for it!"
"Abe, these aren't normal kids, these are Gen-Z kids, they believe anything you tell them!
"Morty, you're a genius!!!"
And Morty and Abe lived happily ever after.
