If I had a vote for father of the year, my vote would go to Mike Mika for his hacked Donkey Kong version he put together for his daughter.
When Mika's daughter got into the classic video game, she eventually asked how she couldn't play as Princess Pauline instead of Mario. When Mika told her that it wasn't an option in the game, she got sad about it. So Mika did what any reasonable parent would do, he hacked Donkey Kong for his daughter. This new version of Donkey Kong swaps the gender roles, with Princess Pauline now running through the gauntlet of rolling barrels and hopping obstacles.
It wasn't the easiest of procedures to create the hacked Donkey Kong, but as the YouTube video shows, Mika was so successful that you'd never know that the original version had Mario jumping through the gauntlet. Seriously, Mike Mika would be any geek's choice for father of the year.
