AppTOKYO (!!!) is offering their new "Happy Birthday Cake" iPhone app for free for one month, so you can literally do as little as possible to celebrate somebody's birthday.

The app provides a space to type in that sorta-lucky person's name on the "cake," and then he or she can blow out the "candles" by blowing saliva all over your iPhone. But once the candles are blown out (and it looks like that takes a bit of effort), the birthday boy or girl will get a nice round of applause for being a good sport. Check out the video below.
