Mom's don't forget their kid's birthdays, right? Well, this mom did and it paid off. Antoinette Ousley from Detroit won a pretty good chunk of money, only because she screwed up on the age of one of her kids.

She usually plays the lotto using a combination of her kids birth dates and their ages. One of her kids happen to turn 20 recently and she forgot. So, she's filling out her lotto ticket numbers and marks 19 instead of 20.

By playing the wrong age of her son and marking 19 instead of 20, she matched five numbers and won herself the nice sum of $78,000.

Anttoinette now has enough for a down payment on a new house and it's all because she made the mistake of forgetting her son's age.

I like to see someone screw up so bad, it turns out good.
