What is the most annoying toy in your house?

Mine is this:

My son loves this thing. He likes to be pushed around the house in it. What's annoying is the sound just goes on randomly and then gets stuck like a broken record and grates on your nerves until you jump up and start banging on buttons for it to stop. And then it still doesn't stop. Aaaack! The on/off button is useless. This thing has a mind of its own.

This is our annoying toy http://www.amazon.com/LeapFrog-Alphabet-Pal%C2%AE-Cater...id=1208723574&sr=1-8 It has a habit of going off at random times like in the middle of the night
This one too, http://www.amazon.com/Fisher-Price%C2%AE-Laugh-Learn-Le...id=1208723708&sr=1-1 My DD loves this toy and always wants it while we are in the car. All the movement seems to make it constantly sing.

The ones that sound in the middle of the night are the worst! My daughter had a remote control car that would randomly start going around in circles at all hours, and she has a little doll that says the 23rd psalm when you squeeze it; only it also randomly starts "talking" in the middle of the night and will scare the cr** out of you!

I have a new one.

Get this.
Tonight at dinner all of a sudden we hear a high-pitched noise. It's steady and super annoying and giving us all a headache. My DH jumps up and starts investigating. He turns off the TV, the lights, the fan, and is checking our smoke alarms and all of our technology...this went on for like 40 minutes. We were all getting headaches and our dinner was getting cold as we tried to figure it out. It was just maddening.
Finally we think to start checking Jack's toys and...it's this silly little phone malfunctioning on the floor near the dinner table.
