An Angry Giraffe Chases Down Tourists on a Safari

Some people on a safari in South Africa filmed a giraffe chasing their truck so fast that it passed them, and then stopped defiantly on a shallow stream in front of them.

They stopped too, and then went in reverse for a while, but it kept following.  The clip ends soon after that.  According to one report the giraffe did eventually give up, and nobody was injured.
