Thing 20: YouTube.

YouTube is an amazing site, and one can spend hours surfing various videos. My friend G likes to search for "laughing babies" now and then just to keep herself sane. I use YouTube to view Japanese comedy bits and TV shows; it's cheap, fast, and you can search for content in Japanese too!

I was at CLA this year and saw the Library Cheer. I was happy to find it on YouTube so that everyone can learn it!
