23andMe: What better way to make up for neglecting your girlfriend than by giving her the most personal gift possible: a detailed analysis of her genetic code. She'll be able to learn about her descendants as well as get clued in on what sorts of diseases she needs to look out for in the future. And as an added bonus, all that data she'll get will require a good amount of time for her to go through. Time you can spend playing video games. $300-$500 [23 and Me]
