These three small words spoken by Walter are seen twice in the series. The first in live action, as a sarcastic retort after Hank dryly joked he might have been the W.W. that was Heisenberg. The second time? A brief flashback to that same first moment, when Hank finally realises that Walter is indeed the W.W. that is Heisenberg at the conclusion of Season 5's first half. In typical Breaking Bad fashion this second moment, a major turning point in the whole series was given its own particular surreal and humorous twist by occurring whilst Hank was taking a dump. There was even a particular sound effect of a small nugget hitting the water which AMC decided to edit out of the end of the live broadcast. Apparently Breaking Bad was sometimes too Breaking Bad.
