Putting things together and watching what you've built work correctly can be very gratifying.

This father has put together a model airplane which his wife says will fly all the way across his decent-sized front lawn if he flies it right.

But that's the important part. You need to fly it right.

Maybe this dad didn't read the instructions on how to do that. Or maybe this simple task just isn't that simple for the average man.

Either way, he doesn't fly it right since it circles right back and hits him in the face. IN THE FAAAAACE!
