Oh, I got two legs from my hips to the ground, and

When I move 'em they walk around, and

When I lift 'em they climb the stairs, and

When I shave 'em they ain't got hairs

- Monty Python

If ever a song could have been written about me it's that one, for I too have two legs which react in all the ways described above. I have always had two legs, and I use them on most days, in fact almost every day.
