I know. This is sarcasm but meant with good intent: It's kinda like how does a posi-track rear end on a plymouth work or how does a rainbow get made........It just does. (I stole that from a movie......"Joe Dirt", a great show starring David Spade)
I think it is one of the mysteries of life. The itch "moves" away from where the person is scratching. The itch is evil!!!!
Kinda like onemandog said, I guess the itch just likes to play tag, but never ends up being "it" haha ;)
Ikr it drives me crazy
Mmmm hmmmm great show
