I was collecting these for a while, in connection with my more
systematic exploration of the Lexical Clone construction (a.k.a.
Doubles, Contrastive Focus Reduplication), as in "No, what I wanted
together".  My hypothesis was that the emphatic triple (= 'and
nothing else matters') emerged for this function (and I did have a
bunch of others, but they didn't reveal anything earthshattering)
because the double was pre-empted for the modificational use.  Of
course, whenever I presented anything on those triples, someone would
quote the line from the Lewis Carroll epic poem, The Hunting of the
Snark: "What I tell you three times is true".   A quick web search
indicates that you wouldn't be the first to refer to this pattern as
"The Rule of Three".  I don't know of any systematic research, though.
