When small children drop cheerios all over the floor and an adult later steps on one. Instead of exploding like a landmind, you hear a crunch and the cheerio turns to a fine powder that is almost impossible to clean up without a vacuum.
Heather: "Anna please eat your cheerios in the chair!!!"
Anna: "OK Mommy!" (Running off with cheerios in hand to see what is outside leaving a trail of cheerios.)
Tom: (Wakes from sleep, another long night of taking care of the screaming kids) "Oh I am so tired.." CRUNCH "Oh damn it, I just stepped on a cheerio landmind. Get the vacuum!!! ANNNNAAAAA!!!!!!"
