BeOS had is_computer_on() and is_computer_on_fire() APIs:

  int32 is_computer_on(void)

  Returns 1 if the computer is on. If the computer isn't on, the value returned
  by this function is undefined.

  double is_computer_on_fire(void)

  Returns the temperature of the motherboard if the computer is currently on
  fire. If the computer isn't on fire, the function returns some other value.

Another Good one from Objective C:

2012-08-31 00:26:19.773 App[1676:907] * -[__NSCFCalendar components:fromDate:toDate:options:]: fromDate cannot be nil

I mean really, what do you think that operation is supposed to mean with a nil fromDate?

An exception has been avoided for now.

A few of these errors are going to be reported with this complaint, then further violations will simply silently do whatever random thing results from the nil.

Here is the backtrace where this occurred this time (some frames may be missing due to compiler optimizations):
