Do you remember playing with the jack-in-the-box toy as a child? You knew that if you kept winding it up, eventually jack was going to burst out of the top and startle you!Many of you found old jack-in-the-box an annoying toy and confined it to the toy box.....Well, it reminds me of pop-ups on the internet. Eventhough you know that when you get on the internet there is a good chance a pop-up will present itself, you always act surprised and somewhat violated.But as irritating as they are, pop-up.
