The Box Dilemma

I came back from shopping with the kids today and there was a box on the front porch.  The kids of course eagerly grabbed it and started shaking it, and wondering what was inside.  

"I'm going to die of not knowing what is in this box!" was the exact wording.

Now, I know what's in the box because Master told me.  It's obviously from The Stockroom because there are no markings on the outside indicating where it came from.  

So... my dilemma.   How to get my present out without telling the kids what's inside or having them die, actually die!, of curiosity?

Make something up, or just be vague and mysterious?

I hightailed it upstairs with my box, closed the bedroom door and opened the package. 

When I came out, I told them it was a lollipop and "stuff for mom".    I couldn't think of anything more creative or at all plausible.  

They lost interest pretty quickly when they started making cookies, but I have a feeling they are going to ask Master what was in there when he gets home.  

(I'm thinking maybe we should have a story to stick to?)

Oh, and I suppose I won't make you all die of curiosity!
