:::I don't want to be difficult, but I think a lengthy digression into fish would require a reliable source that not only details the "fish" example but specifically links it to the "buffalo" sentence. And besides that, I don't think "fish" really works. If I were fishing for fish, I wouldn't say that I was "fishing fish". To me, that doesn't make sense without the "for". Fish might fish for fish, but they don't "fish fish".
