When humans were young, they were pushed around in strollers. When they were old, they were pushed around in wheelchairs. In between, they were just pushed around.

My mother used to take me to flea markets in my stroller and I would just rummage through the piles. You've got to dig through the overstuffed racks that everyone else just walks by. It's the only way to find the cool stuff.

I remember my wife and I used to get on plane and see everybody else with their babies. They'd be putting strollers and car seats up above and we'd think: Oh please Lord don't make us go through that.
