Beware of Snakes

Two snakes were out taking a stroll when one turns to the other and asks, "Are we poisonous?"

"Why, yes we are," says the second.

Again the first snake asks, "Are you sure we're poisonous?"

"Yes, we are very poisonous."

Again the snake asked, "Are we really really poisonous?"

"Yes, we are really really poisonous. In fact, we're the most poisonous snakes in the world. Why do you ask?"

"I just bit my lip!"
