Well, one day, I heard a siren that sounded like the normal siren only distant and my father claimed that the neighboring town had a "shark siren".
My mother thought that sounded a bit weird, and then my father realized that he'd probably been lied to as a kid and bought it all his life! (He's 45, so he'd be believing the lie for decades!). He suspected either his parents, or this one friend he's had for a long time were the ones to lie to him.
