the case of the missing playdoh

"Trev, where's that yellow playdoh? Here's the cannister. What did you do with it when I asked you to pick it up off the (ahem - livingroom) carpet?"
Around and around he goes - looking up, looking in the sky, looking at pictures.... all the obvious places.
'Bout five minutes goes by. Obviously he hasn't a clue -- it was, after all three or four minutes before.

"Mom," Little Son comes into the kitchen. "I hate to tell you this... but I have hidden the playdoh! And it's Your job to find it! (conspiratorially now) You'll have to go around the world, and into some very dangerous places to look for it!"
I actually laughed - I couldn't help it.
"Find it, please, Son." (I'm not The Worst - I'd help, but I have a list of to-do's myself that is pretty long.)
Another five minutes of looking in all the obvious places.
"Mom - I know this is hard to believe- but I was in my room, experimenting, and I made the playdoh invisible!!"
Another burst of laughter.
Cheeky monkey.
