What's the most exotic pet you've seen someone have?

My aunt worked as a zoo vet, and was one of the people animal control would call if they found an exotic animal and didn’t know what to do with it. As a result I grew up being able to casually play with several different species of monkeys, as well as an asshole African grey parrot. When I was in high school she even fostered a serval cat for a short time till they could find a more permanent facility.
