I was 6 years old that day. I was alone in the house, in my bedroom watching an old cartoon called Steamboat Willie. Mom was at work and Dad went out grocery shopping. I heard something out of my bedroom and saw a shadowy figure passing by. I decided to get up and take a look at it. I walked out of my bedroom and I saw a balloon. The color of it was white. I picked it up and saw a bag of plastic baby doll parts holding it down to prevent it from floating freely. I looked downstairs and saw a hand that quickly disappeared. But there was another balloon and that color was red. I went downstairs to pick it up and the same plastic bag with the same plastic baby doll parts holding it down. Then I looked down another set of stairs and saw the hand going into the kitchen. Next to it, you guessed it. Another balloon with a plastic bag and baby doll parts. The color of this balloon was black. I went down this set and picked it up and heard something fall in the kitchen. I decided to walk into the kitchen when a can rolled across the kitchen floor. I stopped for a brief moment then kept walking. I looked around the corner of the kitchen counter and saw an old man. He was so dusty and crusty, he looked like he just emerged from volcanic ash. And his teeth looked like shark teeth. He was just crouching there and started laughing silently as if he was anticipating to see me. As a kid, I wasn't scared or anything. Just curious to what he wanted. He began to make these hand gestures as if he was doing some magic trick. He showed me the palm of his hands, made these gestures and out popped a bouncy ball. I'll admit, I was impressed because I thought that was pretty cool. Then he let the ball fell out of his hand and it rolled towards me. I picked it up and decided to keep it. He started laughing again as if he's glad I accepted it. Then he reached behind himself and started wiping his face. He wiped his eyebrows, his cheeks, his mouth, and his nose with blood. I was wondering where the blood came from and felt a little scared. Then, he made another hand gesture as if he did another magic trick and revealed where the blood came from. It was from my mom. I was shocked and my mouth dropped. She was wrapped in plastics and I could see her torso was sliced opened. I looked into her eyes and saw her take one last breath as if she wanted to say something... But then the life in her eyes faded. My mom... Was dead. He kept laughing maniacally and kept wiping the blood on his face. Then he came up to me, put his finger on my mouth and said, "shhh". That's when I heard the front door open and I quickly looked out to the living room. Dad was home. I looked back and he was gone. The old man disappeared as if he was never here. Dad came into the kitchen and before he could even say hi, he saw mom and dropped the bags. He started yelling and crying then quickly called the police. He couldn't believe it as much as I couldn't either. The police arrived within 10 minutes and started investigating the murder of my mother. The cops asked me if I saw anything and I told them I did. I said I saw an old man who was crouching. I described everything I could about this thing and told them he gave me the balloon and the ball. My dad asked, "who gave you the balloon and the ball?" I replied, "The Smiling Man."
Yeah, there is another version. A guy walking down the street at night with a huge creepy smile and walking funny as if he's dancing and walking at the same time.
