Often wrongly touted as a weapons of mass destruction, anthrax is in fact used as a 'weapon of mass death', as it causes very little destruction, and lots of death.
"Anthrax killed several thousand people today, but caused little destruction."

1. An 80s heavy/thrash metal band. Part of the Big 4 of Thrash, consisting of them, Metallica, Megadeth, and Slayer. Did some stuff with Public Enemy that many people liked, but i personally hated. Overall, Antrhax is a great thrash metal band that gives you a Fistful of Metal! (Anthrax fans should get that)

2. A white powder, deadly when inhaled. Often used by terrorists in envelopes so, when opened, the opener would be doomed.
1. Anthrax's song Madhouse is one of my favorite songs.

2. Oh, mails here! Let's see here...goddamit...
