Blanket Baby
When my parents were having trouble getting my brother to give up his blankie… I told, in secret, that the reason he loved the blanket so much was that it was the blanket we found him wrapped in… in a dumpster behind K-Mart (a big box grocer/good store for those unfamiliar).
I thought it was hilarious (I believe I was around 9 at the time) but it turns out that the little guy believed me. Years later he blurts out at the dinner table “WHY DID YOU NEVER TELL ME YOU FOUND ME IN A DUMPSTER?!?”
As you can imagine my parents were as “What the eff?” as can be. Story credit: Reddit / MyWifesBusty
