Even the most passive looking animals can turn quite aggressive when you encroach on their territory. Take the ostrich for example. Legend has it that, when they are frightened, they bury their heads in the sand. Well, the ostrich in this video obviously hasn't watched Wild Kingdom, because he/she gives a pair of cyclist a real run for their money in this video.

The whole video reminds me of the classic Warner Brothers Roadrunner cartoons except for the fact that, at least in this video, it's the bird doing the chasing. There are also no ACME products that don't work.

This video has gone crazy on the internet with over a million views. Why not make it a million and one?
