I don't remember what channel it was on, Kitten. It wasn't a series, it was a movie. I always look for it in the listings, but have only seen it once while browsing through a friends satelite guide (how DO you spell that....lol). I was thrilled to pieces, when they told me they would tape it for me, only to have the power go out THAT NIGHT.
The footage itself was documentary, but it was the narration that was so well done.....quite comical. I remember the footage of the chimps and elephants who gorged themselves on fallen fruit that had fermented....a wee sad for the elephants, but the chimps absolutely made the best of it. Cartwheeling and generally acting like a typical bunch of yahoos.
