Humor, to be comprehensible to anybody, must be built upon a foundation with which he is familiar. If he can't see the foundation the superstructure is to him merely a freak -- like the Flatiron building without any visible means of support -- something that ought to be arrested.
Mark TwainIt is human life. We are blown upon the world; we float buoyantly upon the summer air a little while, complacently showing off our grace of form and our dainty iridescent colors; then we vanish with a little puff, leaving nothing behind but a memory - and sometimes not even that. I suppose that at those solemn times when we wake in the deeps of the night and reflect, there is not one of us who is not willing to confess that he is really only a soap-bubble, and as little worth the making.
