@Lordofdark: Sure, nothing wrong with posting it as long as you give credit.
@BusinessCat: I think you're correct! A rattle is a kids' toy, there are some people who play with snakes (snake charmers, herpetologists), and a rattlesnake isn't very playful at all.
@Lordofdark A rattlesnake is a specific type of snake. It's venomous and gets its name from the threatening shaking of their tails, which sound like rattles.
I turn, but always stay in place. I help remove obstacles, thought I cannot lift a thing. Though I am lifeless, I'll still shake your hand. But forget my match, and I may leave you out in the cold.
