Who was the peron who sat o n the fence?

humpdy dumpdy, and he broke it!! :)

song:

humpdy dumpdy sat on a wall, humpdy dumpdy had a great fall, all the kings horses and all the kings men, put humpdy dumpdy together again.....

kinda a dumb song bt he fell and broke into pieces and everybody put him back together. (its a fairytale type thing)
