We recently moved all of the sofa cushions off the sofa. 

We discovered:

• 4 Lego people
• 8 Lego bricks
• 12 raisins
• A spaceman (toy size not a real one!)
• Lots of crumbs and random food scatterings
• A book

We don't allow our kids to eat upstairs (expect raisins and popcorn on film nights) but we know they sneak upstairs with odd bits of food when we are not looking.  Little did we know that rather than eat the food they ground it into little bits and hid it under the sofa cushions!

This image does not really do it justice as hubby had already moved the bits he did not want to hoover up:
