Though it pains me to admit that I sometimes read the Torygraph (Know thy enemy!), I will have to come out of the closet now. But just to draw your attention to a bunch of very nice photos of various animals (some cute, some disturbing) at play with a male of the species Homo sapiens with photogenically unruly hair (already before the adolescent gorrilas had ruffled it).
Yes, it's David Attenborough, who has been doing this kind of thing for fifty years or so. Well done, David. Keep up the good work!
