When I was in Nepal, we went to the Royal Chitwan National Park. Basically a wildlife jungle-type environ, the most prominent photo used to advertise the park to tourists was one where two elephants are going at it. The male proboscis is clearly visible (and nicely proportioned too) and there’s even a crazy Nepali elephant driver riding on top of the male elephant. Anyhow, something about two animals having sex always draws human interest.
