Well as I see it, if we can stick big enough rocket engines onto the moon, we could possibly crash it onto earth, maybe aim it at some country nobody cares about, like africa. Then when the dust settles about 150 years later, the survivors can crack "yo mamma" jokes like there is no tommorrow. Oh yeah.

...Earth, on the other hand, is about 6,250km. (that particular crater is 130km wide)
I would also guess that Mimas' density is, on the average, less than Earth's, so one big meteor would be able to do that. That impact actually caused the opposing side of the moon to fracture - so comparatively speaking, if a rock big enough to cause a 2000km diameter crater came...Well, then we'd be screwed.
Things big enough for that particular crater have hit Earth before (or, marginally close to the size of that). Notably in areas like Siberia and the Yucatan Penninsula. That'd be the one hypothesized to have killed off the dinosaurs (but it's thought by some to be too small) - so you can thank it for helping mammals win dominion over the Earth.
Remember that the reason you don't see giant craters on the Earth is because we have intense weather and plate tectonics to erode them away (along with oceans, which probably hide some unknown craters).
Remember that Mars has weather too, so many craters from the Martian surface have slowly been worn away - but you can still see many craters quite easily.
[also note that the 'craters' in the east-central part of the map are volcanoes (hence the Olympus Mons and various other Mons-es) - the southern half of the picture is where the craters are most distinct] <img src='http://www.the-planet-mars.com/pictures/map-mars.jpg' border='0' alt='user posted image' />
We're also the only known planet to feature plate tectonics, so...yay, us.
....So...yea...Big stuff has hit us before, it'll get around to doing it again (but the older the universe becomes, the more spread out things become and the more things have already hit something (leaving few things left to fly around).

We need an Earth equivalent of Herschel, pronto!

Then we'll start talking Fat momma jokes XD
But nonetheless, asteroids won't hit us for at least 400 years or so. So we won't get to see doomsday meteors or asteroids. Booooo.
