Question about killing an elephant

Alright, so I just had this strange thought. Imagine you're just standing peacefully at a street corner, whether it's in the city or in your neighborhood, and out of nowhere!

A ten ton African Bush Elephant is charging at you with murder in it's beady little eyes.


So what to do? You can't really outrun this mass of killer grey, so you've kinda gotta kill it. My real question and inquiry, is how would you do it? I guess you can take a few liberties, such as being able to outrun it long enough to grab some makeshift weaponry or something, but the end result has to be the same: the elephant must die!

Jam it back in, in the dark.
