The longer and more carefully we look at a funny story, the sadder it becomes.

"But there is nothing enduring in the world, and therefore even joy in the second minute is already not as acute as in the first; in the third minute it becomes still weaker and finally merges unnoticeably with the usual condition of the soul, as a circle on the water, caused by the fall of a pebble, finally merges with the smooth surface."

Nikolai Gogol
