My mom tried to put me in one of them fancy newfangled collapsible strollers, but I figured out how to work the lever that collapsed it. I used to delight in pulling the lever at the worst possible times, so she had to get one of those old-fashioned 30's style strollers instead. We still have it in the basement.
Once I started seriously walking, she had to put me in a harness and a leash. Actually, I like that a whole lot better than holding her hand.
