a head-scratcher

I've begun the packing process. I've found some interesting things: a $20 Target gift card, pictures I'd forgotten about, a whistle/compass combo I thought I'd lost, and many things that are now in the Freecycle pile. But here's the real mystery: a decorative plaque with a saying on it. I have no recollection of the plaque, where it came from, or why I have it. Here's what it says:

May the Light always find you on a dreary day.
When you need to be home, may you find your way.
May you always have courage to take a chance,
And never find frogs in your underpants.
--A Middle-aged Scandinavian

Any guesses on where this came from? Because I am, as you may guess, scratching my head on this one.
