From the “Only in Mexico” and “Not The Onion” archives, comes Cambiados al nacer (Switched at Birth,) an initiative launched by a group of citizens in Toluca, Mexico, informing people born between July 23 and 24, 1974 that they might have been given to the wrong set of parents.
So far, the Facebook page of Cambiados al nacer has a mere 418 followers, but heck, they even got a story in a local newspaper, aptly titled: Se equivocó la cigüeña (The Stork Made a Mistake.)
I personally find this very amusing, mostly because I was not born in Toluca in 1974, but if you did, you should be worried. Very. Worried.
