BD was testing the latest release of his project's code, and he came upon a situation where the code wasn't acting as expected. He wrote up the defect, and the developer went to talk to him. The developer told BD that it wasn't a defect, because the code matched the spec. The developer then proceeded to pull the spec out and show BD. BD agreed that the spec the developer had printed did indeed say that, but he told the developer that he didn't have the latest version of the spec.
The developer pointed to the paper and said that that's what the spec said, so it wasn't a defect. BD pointed to the paper and said that it wasn't the latest version of the spec, so it was a defect. The developer tapped the paper and said that the code matched the spec, so it wasn't wrong.
BD having come to the end of his patience for the situation, picked up his pencil and marked through parts of the paper. He then told the developer that the code no longer matched the spec, so it needed to be changed. The developer stood there for several minutes looking at the paper, before he picked it up and walked away...beaten.
