Send a birthday greeting by phone
Want to wish somebody a happy birthday, but don't want to make it just another Hallmark moment? Maybe you should check out BirthdayDialer.com.
A free service, these guys will send your greeting along to the lucky Birthday Boy (or Girl). You can choose from several different greetings—there's a traditional rendition of "Happy Birthday to You", a banjo version, and even a "Bollywood Birthday". And of course, there's Marilyn Monroe's breathy "Happy Birthday Mr President". There's a generic "happy birthday" message that goes out along with the fancy-schmantzy one. Your call is placed in real time, so you'll need to remember to visit the site on your friend's birthday.
These guys also offer a paid version, where you get to schedule the call, and add your own personal message as well.
