Ok I got one:
One time I was going on a bike ride (I was 10 I think) and I got really ahead of my mom who was walking. So I came to this really steep hill and went right down it. Suddenly, my brakes failed and I couldn't stop or even slow down.
Then perfect timing, a car was pulling up into their driveway (unaware that a kid was speeding down a hill uncontrollably with broken brakes). So soon enough, I crashed right into the car and slid down it like in cartoons.
The couple quickly got out to see if I was okay, which I was. So I said sorry and went home. Later, my mom eventually came to the couple and they explained to her that her daughter had just ran her bike into their car. My mom (thinking they were talking about my sister Devon) was sooo angry and was yelling at Devon so much for what had happened. Devon was so oblivious and just took the yelling like she had actually done it (I was watching her getting yelled at through a window and was lmao

)
Anyways a few hours later, my mom got the real side of the story from my brother and I or course got into such big trouble.
