Pick an item that you frequently misplace and find again (wallet, keys, ID, pen, etc . . .) and ask "Where is my [wallet]?"
Answer the question for the person above you. Just take a guess (in your desk drawer, on the nightstand, in your pocket . . .) e.g., "Your wallet is on your nightstand."
Then end your post with "But where is my . . ."
Example:
First poster: "Where are my keys?
Next poster: "Your keys are on the toilet tank. But where is my iPod?"
Third poster: "Your iPod is in your backpack. But where is my lighter?"
And it you want to be bizarre, go for it.
Ok, time to start.
Where are my Netflix DVDs?
