Press android version thrice took me to another screen which shows big Jellybean logo! When i pressed settings> About phone >Android version thrice quickly, it took me to another screen which displays Android version with Red  Logo. I wonder this behavior is common in all Android Flavors. I have galaxy Nexus with Jellybean 4.2.2
Its called Easter egg. All android versions contain same feature. You just hold that screen for 2 sec, and some more will be displayed.
