Silent and almost deadly

What is it about farts that we find so amusing? Is it the sound, the smell or the fact that we can release a cloud of gas without having to worry about anyone finding out the source? Whatever the reason may be it is only funny when we are the ones delivering it.  Unfortunately, I was on the receiving end of one of those silent and almost deadly farts this morning. I was on my way to work sitting in a single seat on the end of a train car. The train was unusually crowded and several people had to stand all the way in to town. At a certain point during my journey I started to smell what I can only describe as the most retched smell I have ever smelled. It was as if something had crawled out of the deepest bowels of Hell and then died again. The stench was so bad I had to cover my nose for a few minutes. Luckily the train had pulled into a station and doors opened. The burst of fresh air was amazing. To my surprise nobody else seemed to have noticed this chemical attack. They all just went about their business.

Whoever was responsible for this GROSS smell...You may want to see a doctor about it.
