Snowy came from Snow Pea. That's what we were supposed to call him. It lasted about two days and morphed into Snowy. (It's easier to yell )

And Mr. Jones-

Well, my husband and I were spending a leisurely day in Croatia, when a man walked up with a dog. Obviously he didn't speak much English at all (and I spoke zero Croatian, to be fair) but he did keep saying: Mr. Jones... Mr Jones... and pointing to his dog.
I thought it was dignified.
So we have a Mr. Jones!
