When I was 15 I fooled some classmates and a couple teachers into believing that I had fathered a kid at 11. I made up a story that he had been conceived at summer camp four years earlier and been born the following May, which would have made him 3 years old at the time of the prank. Basically, I said that the mother had recently contacted me, informing me that I was the father of her son, a "fact" of which I was unaware until then. I had my older sister write the letter so it would differ from my handwriting and look more girlish, and I even borrowed a photo of one of her college friends and her baby to make it more believable. My older brother also went along with it, but I had to bribe him.
Anyway, people fell for it. I made sure my mom never found out by begging my friends not to tell her anything. My reason was because I didn't want to upset her with the baby news when in reality I didn't want to be grounded for fibbing. I knew that if my mother discovered what I'd done, knowing her, she'd make me apologize to everyone individually. Eventually it got old playing the part and I eagerly welcomed summer vacation once school was out. I did end up confessing when the new school year began, but no one thought it was very funny. Needless to say, I was given the silent treatment.
Salve, Regina, Mater misericordiae
Vita, dulcedo, et spes nostra
Salve, Salve Regina
Ad te clamamus exsules filii Eva
Ad te suspiramus, gementes et flentes
O clemens O pia
