If you're stuck taking care of your spawn there's a good chance you aren't getting your kicks racing your fancy car around. Damn babies take up a lot of your free time. But hey, that doesn't mean you can't get a taste for speed and instill a healthy fear of his father into Junior at the same time.
The Strollometer is a speedometer for strollers, letting you see how fast you're pushing the kid around the block. That means you can make calculations like if the block is a half mile around and you need to get back to the house in five minutes to catch the start of the game you need to keep that stroller moving at an average of 6 MPH. Now that's parenting!
