Just in case any American viewers don't know, what Europeans call elk (as in this case) is what Americans would call moose. (What we call elk is something different).
"In another treat we already had this case and we agreed to call the American (sub) species Moose and the European (sub) species Elk." (quoted from above).
And for American viewers, what he calls "treat" is what we would call "thread!"
(I am sure that was just a typo, but I can't resist having some fun).
