TNT was used extensively in blowing the fuck out of mountains to build railroads. You know how doctors give heart-attack victims a little nitroglycerine pill to put under their tongues when they feel a heart attack coming on? You know why putting a nitroglycerine tablet under your tongue helps? You know HOW they... the doctors... discovered this fact? It was the Irish. It involved excessive alcohol drinking. It involved hangovers and the lack of hangovers among the TNT blasting crew. Mostly Irish. The blasting crew didn't suffer bad hangovers like the rest of the workers because they were exposed to the nitroglycerine in the dynamite. As a direct result of this study, it was determined that a side effect of nitroglycerine exposure results in a rapid expansion of small blood vessels in the heart and brain. When you have a hangover headache, it's because your little brain blood vessels have been displaced with alcohol molecules. Your best bet is to chew a stick of dynamite.
