Piggybank Ride

I love it when little kids just say things that aren't quite in line with what we do. An instance today happened when a girl of 6 or so was being given a piggyback ride, said:

Yay! I'm gettin' a piggy bank ride!

This was more just for fun, and everyone enjoys them, and I'm forever calling them piggy bank rides. Already I didn't know the etymology of piggyback, so this just seals the deal. Conversely, a different child on another occasion was referring to my at-the-time-existent pony-tail as such, but I thought she said pointy-tail, which I just loved the sound of.
