From http://developer.android.com/reference/android/os/UserManager.html, we can find a weird string variable named DISALLOW_FUN, which Specifies if the user is not allowed to have fun.
However, I cannot understand what it means.
Any explanation?
AFAIK, it is an Easter egg, along the lines of GRAVITY_DEATH_STAR_I
and many other similar jokes in the SDK.
