Got a pretty box from Amazon. Opened it to find:

http://www.amazon.com/Christmas-Lump-Coal-With-Gift/dp/B001LA585A/ref=pd_sbs_misc_3

The Christmas Lump of Coal package, with a note that said, "Sorry man, You didn't give me any details in your redditgifts profile. Hope this keeps you warm during Christmas."

There was nothing else in the box.

Update: I feel like the biggest grouch in the world right now. My Secret Santa had sent a second gift that I did not find until today, and it was a very considerable Amazon Giftcard in an even prettier box.

If anyone else has gotten troll gifts for Secret Santa, I hope that your Secret Santa was only playing a joke; I believe now that Reddit is a great community, and that we will always look after our own.

Happy holidays everyone!
