Learn Photoshop While You Laugh Your Head Off
I just realized what's wrong with our entire education system: not enough rap. Witness this Photoshop Tutorial Rap: it's not only hilarious (and NSFW), but also downright informative.
Now you know how to remove red-eye, add a drop shadow to text, and, um, jazz up a line-art unicorn. Granted, you'd probably have to go back and watch the video a few times to really understand the "lessons," but the information is solid.
What other software do you think would benefit from a rap-based tutorial? My first thought: Outlook! ("E-mail filters in the hizzouse!")
