Last night when we went grocery shopping I was looking at what kind of stuff cereal came with these days. Most of them didn't and the ones that did were lame. Things like a discount on movie tickets, how to turn the cereal box into a school folder or a flower station for bees, an ad for the cereal company's website, etc. The only cereal that came with anything was Cocoa Puffs with a twisty straw but you didn't even get a whole straw, it came in pieces and you had to collect them all.
The era of watching Saturday morning cartoons and fishing for toys out of the cereal box has died long ago.
