The Six Stages of Debugging

Just got this from a friend. Probably an known joke but it’s the first time I see it. 

The Six Stages of Debugging

   1. That can’t happen.

   2. That doesn’t happen on my machine.

   3. That shouldn’t happen.

   4. Why does that happen?

   5. Oh, I see.

   6. How did that ever work?

How true this is, isn’t it? Para shared with me that he’s previous boss would say that that the most common phrase you will here from a programmer is – “It works on my machine”. 

I dare you to proove this wrong :).
