That's why he spent a month coding a custom DS version of his girlfriend Tammy Li's favorite game, the color- and shape-matching puzzle title Bejeweled. Once she hit a certain score in his homebrew effort, a marriage proposal would appear on-screen.

Not only did she achieve the score, but, much to Peng's relief, she said yes. "I thought it was pretty cool, in a nerdy way," he said, according to The Associated Press.

After Peng posted on his blog about the proposal in December, it eventually came to the attention of Bejeweled and Peggle creator PopCap Games. The company has since committed to flying the couple out to Seattle for their honeymoon and providing copies of Bejeweled for wedding guests.

"Most video game companies would frown on people manipulating their games," explained PopCap representative Garth Chouteau. "But it won him a woman. As a bunch of geeks, we have to say, 'Bernie, hats off to you.'"
