Hey! Here's an idea!

There’s this little fly, so tiny that even ants don’t bother with it. The female fly pokes a hole in an ant and lays an egg in there. The maggot eats its way up through the ant until it gets inside the head; the ant remains oblivious. Later, this maggot somehow convinces the ant to leave the nest and find a nice moist place, then releases a chemical that makes the ant’s head drop off. The maggot snuggles down in there to metamorphose into adulthood. My point being, I guess, that you shouldn’t trust everything that goes through your head.
