Weird Al Yankovic's "Bob".  The lyrics are all palindromes!

The first Car idiom that comes to mind is "Shifting gears".  Suddenly changing what you are doing/talking about.  Manual transmission for the win!

Memrise is 100% free.  It comes as an app or a website (http://www.memrise.com/), and it has a multitude of languages to choose from.  I've been using it to brush up on my Mandarin vocabulary, and it has a lot of different classes just for that language.  It's definitely worth checking out, and it's a really useful tool.

My name is Sam, and I want to be fluent in Chinese and Russian!  I just got accepted into the University of Florida to get my bachelor's in Chinese, so I'm working on the first one, and after I get a little bit more fluent in Chinese, I'm going to start taking Russian classes!  So hi there, Linguaholic!
