Poll: How long can a baby stay wrapped up under a Christmas tree before it starts crying?

I found a baby this morning in a parking lot at Best Buy. I was going to stand in line to buy a Run DMC cd for my secret santa at work. I found this baby and I thought it would be better than the cd. I wrapped it in some reindeer paper, but now I'm thinking it might cry over the weekend and I don't want the cleaning people at work to get it and sell it on the black market.
