Oh, those whimsical Google nerds. The Mountain View-based search giant may not have Apple's design chops, but it certainly knows how to code a good joke.

We got a taste of that fact on Thursday with the highly popular "Do a Barrel Roll" search trick , which went viral on Twitter and brightened a million work days. But that's only the latest in a long line of quirky features Google has embedded in its products.

Check them out, and let us know in the comments if you have any other favorites.
