Riding along on a train in sweltering heat in Bahrain
Was a young man looking uncannily like Cain,
The first ever murderer that we know of.
But this one here was a show off.
He was not planning to use a club but hexanitrohexaazaisowurtzitane.

_{PS: Hexanitrohexaazaisowurtzitane (commonly known as CL-20 or HNIW) is a polycyclic nitramine compound engineered as one of the most powerful, non-nuclear high explosives in existence.}
