You know, I think we're all being just a bit too flippant about this entire subject.
Just stop and really give it some serious (snicker) thought.
If we've learned anything at all about Science, Geology or History, it's the factual certainty that there were never any earthquakes or any other geophysical activites happening on this planet until AFTER the first appearance of feminine boobage on the scene.
Once this anomoly was uncovered, the earth began to move.
Let's take responsilbilty ladies (well, not me personally - not MY fault) and sing out proudly: "We make the ... earth ... move ... under your feet. We make the sky come tumblin' down......" (I paraphrase of course. My apologies Carole King.)
Just ignore me . . . I'm trying to fulfill my daily snark quota early. I'll be busy later.
