If you've had children's toys around, there is the DISTINCT possibility that you've experienced the phenomenon of the toy that doesn't want to turn off. We had a Micky Mouse play computer that would suddenly go off at random times and make his annoying noises and sing in his shrill voice his little song. The two youngest boys have a monkey that will put ALL those other unpredictable toys to shame.
This CUTE? toy was really a great idea---he has a parachute---you throw him in the air---he squeals this high pitched monkey squeal when he hits the floor. AWWWW--SO CUTE---EXCEPT---he has a mind of his own and goes off at unpredictable times.
While helping pack up in Erie, I slept downstairs on the couch while everyone else is upstairs in bedrooms with thick doors and noise machines running. The EVIL--NO GOOD---POSSESSED--monkey would go off at random times during the night. This was bearable---UNTIL--the night that he had been placed in the mudroom off the front door- RIGHT BY THE DEN! Every thirty minutes ALL night---he squeals and I jump. I am CERTAIN the neighbors could hear him since they keep their windows open and he is in an uninsulated room. Around 3 AM, I finally get up--go get the PEST and take him to the BACK mudroom and the recycle bend-at the back of the house.
He proceeds to protest by going off every 15 minutes the remainder of the night-but my hearing is seriously muffled anyway---POOR NEIGHBORS---I am SURE they wondered why the squealing moved locations but picked up intensity in the middle of the night.
EVIL POSSESSED MONKEY!
