In the word association game, I.m sure there have been words repeated, and I would guess even successive pairs that have recurred. I confess that I am much too lazy (or too sane) to look through the whole thing to check that supposition, but I wonder what the longest repeated string is, and whether there is anyone obsessive enough to have looked??? Perhaps we can figure out some way to divvy up the labor of looking (assuming somebody else shares my curiosity).
