Why is Humpty Dumpty an egg? I mean at what point in the nursery rhyme does it actually mention or even imply that he is an egg yet in all the nursery rhyme books I've seen he is always an egg, why?

If you parked a camel in a car park would you need to buy a pay and display ticket? I imagine it's the same with horses and possible motorbikes, what if you put a pay and display ticket on and the camel ate it though, there would be no point putting one on.

I don't have any more at the moment but I'm sure I will later , feel free to comment with any peculiar questions of your own.
