When I was four and my brother was seven, we each got a GI Joe for Xmas. Instinctively I took of all of their clothes (a 'Mattel' label where the good stuff was supposed to be...so dissappointing!), put them on my softest pillow, made them tangle up into one another, and put a blanket on top. My brother found them like that the next morning, and with a puzzled look, asked me...'What in the world are our GI Joes doing? Are they fighting?!". Well no, they're doing something much more worthwhile.
I was a very precocious little tot!
