Oh no, it's a Cosmic Tsunami!

For a story's sake, let's say a series of enormous gravitational waves caused the fabric of space time to fluctuate. What would that be like for us here on Earth, experiencing the fallout?
I realize that gravitational waves as we know them only alter space-time by incredibly minute increments. But humor me, and let's say that two super-black holes collided and created massive gravitational waves headed towards Earth. I'm trying to wrap my mind around what that would mean for us Earthlings. Earthquakes and other catastrophic damage I imagine, but what about the time element?
I'm interested in both grounded scientific answers ("we'd be dead in an instant so we wouldn't notice anything, duh") as well as fun/silly theoretical spit-balling ("we'd experience brief hiccups of the past before being obliterated, perhaps?")
Apologies in advance for my damnable lack of an astrophysics background.
