People cry out against the sinner, yet it is not the sinful, but the stupid, who are our shame. There is no sin except stupidity.

Whenever a man does a thoroughly stupid thing, it is always from the noblest motives.

Irony is wasted on the stupid

Personally, I have a great admiration for stupidity.

There is more stupidity than hydrogen in the universe, and it has a longer shelf life.

If you pretend to be good, the world takes you very seriously. If you pretend to be bad, it doesn't. Such is the astounding stupidity of optimism.
