The Mobile Giraffe Feeder

The Internet, in all of its constant quest for wholesome content, is making this out to be a friendly giraffe helping a gazelle in distress by plucking off a branch that's stuck in its horns.  I doubt that the gazelle is in that much distress - I once worked with a Speke's gazelle who would frequently trot around with an entire flake of hay impaled on his horns.  As for altruism, I suspect that the giraffe was viewing this as a somewhat novel but ultimately satisfactory feeding experience.  If you were to strap browse to a Roomba and let it loose in the exhibit, you'd probable get the same reaction.
