I came across this recently, it had me in stiches and I have no idea if it's serious.
It's a patent application for walking through walls. There are several gems in here including "Upon reading his explanation, I realized that the thunderstorm is actually a hyperspace physics phenomenom." and my personal favourite "How to generate negative mass, traverse hyperspace and walk through walls, even with a dog".

A quick Google and there are several patents by the same chap JOHN QUINCY ST. CLAIR.
