Here is a hilarious free application for you all to enjoy. Texts From Last Night is an application that links itself to the website of the same name, which is akin to the likes of Twitter and FMYLife all of which have great applications as well.
Using the application you can view all the latest texts that people have sent in to the site and you can even search from within the application your own area code to find people who live nearby who have sent in stuff.
It's rather funny to see what people actually text in to the service, but I really cannot let this go without giving you all a warning. Some of the content found may not be for everyone (read: offensive). Use your own judgement.
