I've never stepped on an elephant's toes. That could quite possibly piss off the elephant, who may respond in kind. Ouch.
I have been sneezed on by an elephant. Many years ago, I did one of those elephant ride excursion thingies in Thailand when I travelling there. The ride went through some very dusty hill country. When it's dusty, one is given to bouts of sneezing. When an elephant sneezes, it raises its trunk up over its head, pointing toward its back. I, of course, was on the back of the elephant.
Actually, I wasn't even on the back, but on the beast's neck/shoulders, so I basically had this elephant snot-cannon staring me in the face for a good chunk of the trip. Elephants can produce a lot of snot. Yes, it was gross. And I had to do laundry after my trip.
Not that I planned it, but on my way home from school today (final exam, last course, certificate completed, yahoo!), I stopped in my favourite used bookstore (Eliot's Books, on Yonge Street) and purchased a volume essays by George Orwell. One of the essays in the book is "Shooting an Elephant". It's not a very long read, but it's quite affecting. Go read it.
