Weird video i still remember

I remember when i was younger, youtube was still quite (around 6 years old) I didnt know to find videos so i decided to type in random things. Eventually, I found a video which shows a man getting killed by another person with a clown costume. I still remember this video and when my dad saw what i was watching, he stopped the video. I actually remember this clearly tho i still think this is a mandela effect or a dream.
