Alright, I will only make science jokes periodically from now on.

Instead, how about some useful instructions?

How to Mail Anthrax (have to put it in spoiler tags for obvious safety reasons)

Step 1:
Buy Anthrax. I recommend Spreading The Disease. Check Amazon, eBay or your local Walmart.

Step 2:
Packaging your Anthrax correctly is important, so make sure you get a padded envelope. To reduce the chance of your package being opened or mishandled, make sure you have written the recipient's name in clear, legible letters.

Step 3:
Be sure to use sufficient postage, so your Anthrax will arrive safely at its intended destination. If you want, you can mark the envelope with instructions, eg. "Caution Fragile, Do Not Bend, Anthrax Enclosed".

Either way, anyone who loves old school metal will certainly appreciate your package.
