Come and get us, Apophis
According to NASA estimates, asteroid Apophis (previously known as 2004 MN4), has a 1 in 5500 chance of hitting Earth in 2036. And some folks think those aren't bad odds (despite warnings), so we're not going to bump the pesky little bugger out of our path (or even change its name, which means, the destroyer).
Besides, last time NASA intentionally crashed into an asteroid, it got sued by an irate Russian astrologer. Who needs that?
