On Christmas Eve 2009, Tracy Hermanstorfer was at a Colorado Springs hospital about to give birth to her first child. But suddenly, disaster struck as Mrs. Hermanstorfer unexpectedly went into cardiac arrest, probably because she realized that she'll now have to get her kid a birthday and a Christmas present at the same time.
After the mother's heartbeat came to a standstill, the doctors tried to at least save her son by performing an emergency cesarean section on the clinically dead woman. They got the baby out but the newborn was very weak with a rapidly diminishing pulse. The staff then handed the dying baby over to Mr. Hermanstorfer, assumingly so he could get a good, close look at his life going straight down the toilet.
That's when the universe yelled "You've been Punk'd!" and Mrs. Hermanstorfer's heart miraculously started beating on its own. Soon after that, her son's pulse stabilized, and he began breathing normally. They both eventually made a full recovery, with the mom not showing any side effects from being technically dead for four minutes.
Other than her sudden craving for human brains.
