The blind cave of eternal night. [ William Shakespeare ]

O comfort-killing Night, image of hell!
Dim register and notary of shame!
Black stage for tragedies and murders fell!
Vast, sin-concealing chaos! nurse of blame!
Blind, muffled bawd! dark harbor for defame!
Grim cave of death! whispering conspirator,
With close-tongued treason and the ravisher! [ William Shakespeare ]

Within a bony, labyrinthean cave,
Reached by the pulse of the aerial wave,
This sibyl, sweet, and mystic sense is found,
Muse, that presides over all the powers of sound. [ Abraham Coles ]

My tears are buried in my heart, like cave-locked fountains sleeping. [ L. B. Landon ]

When I was a kid my favorite relative was Uncle Caveman. After school we'd all go play in his cave, and every once in a while he would eat one of us. It wasn't until later that I found out that Uncle Caveman was a bear. [ Jack Handey, Deep Thoughts ]

I bet a fun thing would be to go way back in time to where there was going to be an eclipse and tell the cave men, If I have come to destroy you, may the sun be blotted out from the sky. Just then the eclipse would start, and they'd probably try to kill you or something, but then you could explain about the rotation of the moon and all, and everyone would get a good laugh. [ Jack Handey, Deep Thoughts ]
