Sorry, forgot yesterday:
"While this was passing between Dick and his companion, one of the boys, a rather supercilious-looking young gentleman, genteelly dressed, and evidently having a very high opinion of his dress and himself, turned suddenly to Dick, and remarked,--
'I've seen you before.'
'Oh, have you?' said Dick, whirling round; 'then p'r'aps you'd like to see me behind.'"
From Ragged Dick (1867).
Update II: last week's ho-quo is here; historic first ho-quo (featuring "Mother Watson") is, on the other hand, here.
Update III: Here's the site of the obviously perverted Horatio Alger Association of Distinguished Americans.
