I've been making friends' birthday cards lately and it's pretty fun. If you throw in a couple of things relevant to their interests it ends up as a hilarious inside-joke picture. It's not actually this dude's birthday yet, but I'm the Unicorn-headed guy in the background and the girl is two pictures of his girlfriend mashed together. What do you do for someone's birthday? Aside from giving presents of course (which I have also been doing)
