Step 1) Convince your young son that he bought a $50,000 Mustang on eBay. Step 2) Film it. Step 3) ??? Step 4) PROFIT!
I’m not sure it’d be my personal parenting style, but the whole “Lie to your kids, make them cry, then publicly embarrass them” certainly seems like an effective method of raising your children. I mean, it won’t make them trust you more or respect you or grow up into useful contributors to society or anything. But it will make them interesting with all of their neuroses and sudden seizures upon seeing people driving Mustangs. And that’s a victory unto itself.
