All technology was created by human hands. Where there's a human, there's a sense of humor. Often, engineers will slip a fun secret into the code of their product—they're known as Easter eggs.

These are little winks and nudges for the audience of the product or service to enjoy. We've seen some fun and surprising Easter eggs in operating systems past and present, but the king of these secrets is everyone's favorite search engine: Google.

Over the years, Google's engineers have stashed many of these hidden treasures into its long list of offerings. Here are nine classic Google Easter eggs for you to entertain yourself with.

1. An Anagram Out of “Anagram”

Google "anagram" for a short lesson on linguistics.

Google the word “anagram”. What's the first thing to pop up? An anagram of anagram–“nag a ram”. Well-played, Google. Well-played.

Things take an even funnier turn when you try to look up the meaning of anagram with the query “Define: anagram” and you see “Did you mean: nerd fame again”.

2. Recursive Recursion

This Google Easter egg is definitely one for the nerds out there.

Another fun one is the word recursion. Recursion, of course, is when something repeats itself in a self-similar way.

When you Google “recursion”, you're given a handy link that lets you do it again. And again, and again.

3. Askew Your Google Experience

Some Google Easter eggs really do go above and beyond.

Here's a fun one, especially if you want to prank a non-techie into thinking something is wrong with their computer.

Type “tilt” or “askew” in Google Search, and the results page will appear tilted by a few degrees.

4. The Bacon Number

Google calculates the Bacon Number of any celebrity instantly.

The Bacon Number is a long-standing Hollywood gag. It stems from the “six degrees of separation” theory that any two people in the world are six or fewer links apart.

For celebrities, there's a “Bacon Number” to suggest that any celebrity is six or fewer links apart from Kevin Bacon, presumably because he has acted in many movies with different casts.

Google's resident movie nerds threw a Bacon Number calculator into the search engine's source code. All you have to do is type “Bacon Number” followed by an actor or celebrity's name, and Google will tell you their Bacon Number and how they're connected to Kevin Bacon.

5. What's The Loneliest Number

Some funny Google jokes hit a little bit too close to home.

It's easy enough to use Google Calculator, but there are probably a few tricks in it that you don't know about yet. Searching for “the answer to life, the universe and everything” delivers the number 42 as a reference to The Hitchhiker's Guide To The Galaxy, and the phrase “once in a blue moon” will give you an equation for that event.

One of the best tricks in this category is to search for “the loneliest number”. Google Calculator comes back at you with the number one which is, as per the song, the loneliest number.

6. Play Atari Breakout In Your Browser

Me getting slaughtered by myself on Google Atari Breakout.

Go to Google Image Search and search for Atari Breakout, the classic arcade game. You'll see the thumbnail results pop up as usual. Wait for a few seconds, however, and your patience will be rewarded.

Suddenly, you'll find yourself playing Breakout in your browser, with the thumbnails acting as bricks. It's our favorite video game-related Easter Egg from Google, although Zerg Rush comes in at a close second.

7. The Universal Language

Google Translate caters to patrons of all walks of life.

Head to Google's Language settings in your Preferences and you can check out the many options available to you there.

Klingon is one popular language option for reasons that should be obvious. There are plenty of other fun languages like Hacker, so browse around.

8. Google in 1998

Google in 1998? Let me take a trip down memory lane.

Google was founded back in 1998, and it obviously looked much different than it does currently.

Want to see what it was like? Just search for “Google in 1998” and the search result page will take on its charmingly retro look from the nineties.

9. Flip a Coin

One of the most useful google Easter eggs of all time.

One of the most adorable Google Easter eggs has got to be their coin flip feature.

Whether you've got a score to settle with a friend or just need to figure out whether you should splurge on tacos this evening, Google's here to help you make any decisions you need to.
