Many people say they "hate the line - 'let's hunt some orc'" or 'let's go hunt some orc.' For the record, this line is "let us hunt some orc." The absence of the contraction "let's" I think elevates it just a bit. I dare say if it had been "let us hunt some orcs" (note the orcs rather than orc) then there would have been no grounds to complain, because the phrase "hunting orcs" is used several times in TTT (book). Nonetheless, personally I basically like this line, and now that I realize it's "let us" and not "let's," I like it even more.
