I'm so glad your stove situation is resolved with mom and sister both happy. (I didn't post on that one, but did read it...)
As for unexpected reactions: My husband loves cribbage and collects boards.. has more than one would think possible. For his birthday a few years ago, I hired our awesome cake-maker friend to make a 'cribbage board' birthday cake, which she did a beautiful job of, creating it to look like an inlay wooden board with tempered white and dark chocolate and all the holes poked through. (We actually put real cribbage pegs in it.) When we brought out the cake, he was in absolute shock. He teared up and told me that "this was the best birthday present anyone's ever given me".
And then, of course, we ate it. But we still have the pictures....and it's still his favorite present.
