Ignorance is bliss

When my manager blurts out to the Client, that this piece of code is a masterpiece, i turn around and laugh within , like a devil , of the joy that i know there are two bugs buried deep within that Masterpiece. He is happy too, because he trusts god,me or himself, and knows that nothing can go wrong. I wonder ... if every man-made thing is such, how haughty we are ... :)
