I proposed by hacking Chrono Trigger
This just might be the nerdiest, yet romantic, proposal I have seen! The guy proposes to his girlfriend by hacking the classic video game Chrono Trigger which she was in the process of playing. He added a new section to the game for her to explore. In the new area of the game he added in interactions that would remind his girlfriend (now wife) of their relationship before finally making it to the point where she would receive a surprise proposal. As amazed as I was that he was able to pull this off, it was no surprise that she said yes!
