celebrity autotune app. Modulates the sound waves of your voice so that you sound exactly like any of your favorite celebrities. Start with the unmistakable big time voices; Arnold Schwarzenegger, Don Pardo, Samuel L. Jackson, Christopher Walken, Ja Rule, Al Pacino. Once you get a solid database, start adding more obscure celebs. Can you imagine the hours of fun you could have prank calling your friends? Just imagine, you prank call one of your buddies a couple hours before you had plans to meet up at a bar to watch the game.
You: Hey buddy! What's new?
Friend/victim: Um, so you won't believe this...but I just got a call from Walt Goggins asking if I was in the market for a used Volkswagon Cabriolet.
You: That's the most ridiculous thing I've ever heard in my life.
...but it won't actually be the most ridiculous thing you ever heard in your life...because you were the one who placed the call to your friend pretending to be Walt Goggins. Oh man!

Features include:
*Telephone number scrambler that will cause the person on the receiving end of the phone call to think they are getting called from either a NYC or LA area code.
*Pro version will include ability to create custom ones that aren't in the database. Just record the voice of the person you want to sound like and the app will take care of the rest. Because let's face it...no matter how many strongly worded e mails you write, the developers are probably never going to get around to adding Renee Stevens. You're just gunna have to wait for the next Spangles commercial and have that finger on the record button.
Also included in the pro version: enabling signature cockamamie cadence. A must have when using Christopher Walken, Jay Z, Paul Harvey, et al.
