This is a true story, doesn't sound it, but it is.

When I was a kid, maybe like 12 or 13 or so, I was having a super bowl party at my house and invited about 6 or so of my friends by to watch the game.

Before too many people showed up, there was just one of my friends there, and we were playing catch with this plush ball with a cartoon face on it that would shout out one of like six different catch phrases whenever it hit something.

We were throwing it back and forth and then one of the times the ball loudly exclaims "SHUT THE FUCK UP".

Me and my friend just stood there, asking each other if the other had heard that, freaking out that that was programmed into the ball to say. So we started hitting the plush ball over and over again, trying to get it to say it again. It never did. Nobody else ever believed us, but the two of us know what we heard. None of the other 6 catch phrases even sounded anything close to "Shut the fuck up" so we could not have been mistaken
