Neatorama has an interesting article by Eddie Deezen which chronicles the menagerie acquired by Elvis both before and after he bought Graceland.
My own personal favorite is the chimpanzee called Scatter. I don’t know how he got that name but judging from his behaviour it was because when the chimp entered a room people would literally scatter (if they had any sense and especially if they were female!). Michael Jackson may well have made Bubbles famous but Scatter, oh boy. They probably had to keep some of his antics very quiet.
