The great idea begins when the teacher encourages students to bring in wild animals to class. It continues when she determines she is an expert on venomous and non-venomous snakes. And this mind puzzler ends when she lets the kids pass the snake around the room. This isn't the Wild Kingdom on the Discovery Channel. Let's just assume this from now on: Snakes can be poisonous. DO NOT touch them. Did she have tarantulas and rabid raccoons crawling around the room too?
