Bought at the garage sale
I was at a garage sale, my cute neighbor was selling all kinds of scifi collectibles for cheap. “How much for these one?” I asked as I showed her a toy gun. “two fifty” she said, I handed her the two dollars and fifty cents and took the gun home. “I swear I have seen this gun before” I said. I walked back home, and browsed the internet looking for some clues about the toy gun. “Maybe it is worth lots of money” I thought. But apart from some drawings of girls holding a similar gun I didn’t find anything. I left the gun inside a drawer and went downstairs. I forgot about the gun for weeks.
