Comment: As Colonel Warden said, evidently |notable - just click on the Colonel's links for |news, books and scholar. Also an entry in Brewer's Dictionary of Phrase and Fable|Brewers predates the Flowers for Algernon use by at least six years but probably more as I am referring to the 1953 edition, could have been there from the start (1870). Have updated the article accordingly. If the outcome of this debate is merge then I would  suggest James while John had had had had had had had had had had had a better effect on the teacher as a better destination - buffalo x8 does not require punctuation & illustrates an entirely different point. Finally whilst the nominator is correct that it is a tongue twister, this fact is incidental to its notability & is not mentioned in the article
