Poisonous Snake Bites Itself

Two snakes were out taking a stroll when the son snake turns to the mother snake and asks: "Mommy! Are we poisonous?"

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

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

"Yes, we are very poisonous."

The baby snake becomes very upset. Again, he asks,
"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!!!"

I just bit my lip!!!
