When your coworkers keep popping by your desk to talk to you, it's really tough to get your work done . . . so you can get back to important things. You know, like aimless web surfing. So here's a pretty brilliant solution.
There's a new app for the Google Chrome web browser called "NOPE." When you click it, the app calls your cell phone. Then you can pick up that call, start having a fake conversation that SEEMS important, and your coworker should walk away.
You can get it for free by Googling "nope chrome."
