When I was about 8 I really wanted a Game Boy but I couldn't afford one. At the time, Walmart was using the slogan "Lower prices everyday" and I took the slogan literally: I thought that every day they would lower the price on every item by a few pennies. So I thought that if I waited long enough, the Game Boy would cost only a few dollars and I could afford it easily!
