In addition, if I were an elephant, I would not have to care how I looked, I could bathe in mud, and roll in the dirt whenever I felt like.
It might be kind of sporting to go thundering through the occasional village as well. I wouldn't actually hurt anyone, I'd just like to watch them run.
I could also occaionally sneak up to a lion while he was napping, put my trunk next to his ear, and trumpet as loud as I could, just to watch him jump.
