Well most of these I already know as
this thread has been done before!!! 
But anyways.... Piggle Humsy originated from a three year old!
Who @ the time was pondering a name for one of her toys...
I have no idea how she managed to come up with such an original name..as normally kids cant think on their own!
Well I liked it so much I asked her permission if I could use it and it's stuck ever since! I use it for almost everything nowadays!
Imagine it... *Do you take miss piggle humsy to be your lawfully wedded wife....*
So that's where it came from!
