Putting the shopping cart back in the cart corrall in a store parking lot. Take the baby out of the stroller, start walking back to the car. Baby starts saying, "Uh-oh! Uh-oh!" I murmur absently, "I know, cart’s gone. Uh-oh!" Or some such. Baby keeps on. "Uh-oh!"

Finally, I turn and see a woman walking after me holding a little shoe in her hand. Shoe from said baby’s foot.

So..the lesson of the day: Always listen, even to babies. They’re trying to tell you something.
