Why do people have goldfish? At least you can get your tarantula out of the aquarium and mess with it. Bastard could haul ass across a dorm room bed if you goosed his ass with a pencil. We fed him crickets but 3 out of 4 crickets would starve to death waiting to get eaten. They would literally crawl right over him sometimes and he'd never move. But one morning there would be nothing left of old Jimminy except a couple of legs. We never got to witness him having dinner unfortunately.
My fraternity brother had a pet boa constrictor. Big fuzzy hair was the style back then...(Can you call it an Afro if it's on a white guy?). Anyways, he would wrap the snake around his neck and shoulders, it would crawl up thru the Afro and poke it's head through the front...kinda of Egyptian pharoh style. We would walk down college avenue, chicks would pass by and freak when they eventually saw what was going on. Good times I tell ya.
I also had a red tailed BOA in college. Super easy pet and people were either intrigued and wanted to touch it or scared shitless and wanted nothing to do with it. Never bit me or anybody, was a very good pet. Ended up living with a girlfriend and sold it to my cousins boyfriend that had like a 8' enclosure in his basement because she was freaking out.
