I googled, but it's tough, because EVERYONE uses this super-secret inside joke between me and my best-friend-from-ninth-grade Nancy these days. On the second page, however, someone said it was a Simpsons quote: Lisa says in regard to Nelson "He's not like anybody I've ever met. He's like a riddle wrapped in an enigma wrapped in a vest." Welp, mystery solved! Nancy and I sure did watch some Simpsons back in the day, I will tell you what.
However, I kept looking, and it turns out that it's orignally a Winston Churchill quote. Referring to Russia, he once said: "It is a riddle wrapped in a mystery inside an enigma; but perhaps there is a key."
So, hey, exciting! Um, for me.
Trees are turning yellow! I love Autumn.
