When it comes to the definition of cheating, just about the only thing that all couples agree on is that if you have sex with someone else, that counts (and even then, it all depends on the kind of relationship you have). Still, in an era of digital personalities and cyber-encounters, there are myriad different ways to get into a cheating gray area. Like Facebook messaging exes. Or going into sexy chatrooms. Or sending R-rated texts. 

So what is "cheating," and what is not? The answer, of course, is purely subjective, and depends on the comfort level of each person in the relationship. Still, it's always good to know what everyone else thinks. And thus the Huffington Post, in partnership with YouGov, set out to poll 1,000 U.S. adults about what they consider to be adulterous behavior. Here are some highlights of the findings:

- 60% say it's cheating if you form a "deep emotional connection" with someone else.
- 48% would consider it cheating if their partner kissed someone else on the lips.
- 24% said messaging an ex on Facebook equals cheating.
- 24% would consider it cheating if their partner went to a strip club.
- 79% of respondents said sending sexy texts or photos to someone else is cheating.

"How do I land?"

It's probably something a pilot should ask long before getting into the cockpit. But one professional skywriter traced the cheeky message above downtown Los Angeles on March 23 as part of an elaborate prank by comedian Kurt Braunohler.

Saw this on the Southwest Freeway yesterday.  I want him as my neighbor.

Google has brought the arcade right to your image search window with its newest celebratory Easter egg game. It’s the 37th birthday of the classic Atari game Breakout, and if you type “Atari Breakout” as a Google image search query, you can play the 1970s brick game right inside your browser. The tiled image results shrink down to form the layers of bricks as the bouncing ball emerges from the bottom of the screen. You can use either the mouse or keyboard arrow keys to control the paddle. Give it a few tries. When you rack up your best score, you can share it on your Google+ page from right inside the game. There will be even more celebrating this week for Google as the Google I/O developer conference kicks off Wednesday in San Francisco at 9 a.m. local time. ABC News will be blogging live from the event as it happens.

In the meantime, you can also check out Google’s other interactive Easter egg at the Google I/O 2013 homepage. Punching in different binary combinations by clicking the giant “I” and “O” on the screen will unlock various engaging pages – IIOIOOII is a Simon game, IIIOOIII is a two-button cat soundboard and IOOOOOOI is a Pong game.
