When I was little, I used to believe there was a monster down in the pipes that woke up when the toilet was flushed. I'd wash my hands first before going for the flush, then run as fast as I could for my room and LEAP onto my bed in case it had followed me- it couldn't be a very big monster, you see. I'd always wait until the sound of the toilet tank refilling finished, and scanned the floor suspiciously before getting back down.
