actually a lot of snakes are harmless and make good pets, but yeah rattlesnakes scare me, almost stepped on a baby diamond-back in CO while hiking one time. I took care of my cousin's ball python for 2 years.
He was pretty cool, never bit me once and I used to feed him by dangling mice in front of him. He would just snatch it right out of my hand. He pretty much thought I was a giant tree to climb on. one time he escaped and lived in my house for seven months. I eventually found him underneath a dresser alive and well, although a little bit dusty.
some cool things about snakes:
-they go blind right before they shed their skin, since they shed the skin over their eyes, it becomes opaque. this is kinda funny because until he shed his skin he wouldnt eat the mice in his cage, sometimes they would sleep in the middle of his coils (mice are pretty dumb)
-they have remnants of legs underneath them. so anyone who doesnt believe in evolution, I always said i had proof in a cage in my house
-they seem very inhuman, but they will do human things like watch tv or sneeze. when they yawn, they unhinge their jaws which looks really funny. they also burp sometimes.
