When I was 8 I couldn't sleep one night. But then, I heard some kind of a low sounding growl that my young mind translated as a lion underneath my bed. It wouldn't stop growling, so I made a mad dash into my parents' room screaming "MOM! MOM! THERE'S A LION UNDER MY BED!"
It turns out that the "lion" was my dad snoring. We bug him about it to this day.
