William Tenn 
Of All Possible Worlds [EPUB ebook] 

Suppose… a man who was blasted into our time from the future arrived without any clothes? Suppose… a man who craved the love of beautiful women got too much of it? Suppose… a conscientious young realtor refused to rent a floor in an office building because it didn’t exist? On such faintly horrifying, delightfully absurd speculations are some of these stories founded. With a keen satiric touch William Tenn uses his insight into contemporary life as a springboard into an absolutely believable, if slightly wacky, future.
