The box I got was unmarked, which was quite suspicious. However, a telltale clue was all I would need for identification. That's for later, though. Lessee what we've got here. Oh, and sorry for crap cell phone pics. It's what I had on hand.

SCIENCE! It actually describes my career pretty well since I've spent the last 10 years or so working in labs in some capacity. I've worked with human, bovine, and mouse blood, liver tissue, cancer cells, white blood cells, all sorts of chemicals, electrical equipment, mechanical testing devices, potent acids and bases,
That, and my philosophy on so many things boils down to "poke it with a stick and see what happens". It doesn't help that I wanted to invest what money I got for Christmas toward
this handy little book here. Hence, I'll soon be making my own potato gun, homemade taser, and thermite.

And here we have a set of cups fashioned in the shape of Ctrl, Alt, and Del keys. A trio very close to my heart considering my 8 year
hatelove affair with my last PC, which would freeze up upon trying to play games that required a lot of memory usage, any web browser, or if you started up Solitaire and a breeze came in through the window. I might not use such a function as much with my new PC, but I still overdo things every so often. The dimensions of the cups are listed at (6.5cm)^3, allowing for just short of 275mL of a beverage to fit in them.

Now to put these puppies to good use and live up to the statement on the shirt. Get over here, Delete.

In this experiment, 120mL of egg nog were mixed with 60mL of frappuccino. The mixture was then heated to approximately 90?C via microwave oven (Sunbeam model no. SBM7500W 120V AC 60Hz single phase). Approximately 25g of hot chocolate mix was dissolved in the mixture, bringing the total volume up to approximately 210mL. Said mixture was air-cooled down to approximately 60?C before oral consumption. The end result is a beverage that provides the benefit of glucose for brain function, chocolate for increased serotonin secretion for feelings of JOOOOY, and caffeine, which acts as a metabolic stimulant to assist in processing the glucose and serotonin. Truly, a beverage that suits any scientist.
Now, according to the billing address on the receipt inside the box my schwag came in, this particular Secret Santa hails from Brazil. The only people I know from Brazil are Blanka and HakureiSM, so I'm going to point the blame at him. To further compound this evidence, the name on said billing address matches up with the delivery address in Haku's post above. Unfortunately, Haku didn't use either of his two Swiss bank accounts to purchase said goods, so it's easy to whittle down potential suspects. Either that, or someone was clever enough to open an account in his neck of the woods with the same name simply to make it easy to pin it on him, or Haku's opening someone else's present in order to deceive us all further. Petty vengeance seekers haven't been ruled out and nor have exceptional lengths to escape detection, either.
Thanks, bro.
