If I had had what I thought I had then what I had would have been something that I had had for a very long time.
I remember watching countdown once where they got 8 in a row! The story was they had had
two contestants on in the past, both with the Christian name "Had" So the hypothetical scenario was both of these Had's playing each other. Then it went Had had had (meaning the first Had managed to make the word had) had Had had had, Had would have won. (meaning if the second Had had made the word had instead of the 2 letter word he made he would have won by 1 point) Told you it was hypothetical!
Had had had, had Had had had, Had would have won.
