Two snakes were out taking a stroll.

Two snakes were out taking a stroll when one turned to the other and asked 'Are we poisonous?'

'Why yes we are' said the second.

The first snake asked 'Are you sure we’re poisonous?'

‘Yes we are very poisonous'.

Again the first snake asked 'Are we really really poisonous?'

'Yes yes, we happen to be the most poisonous snakes in the world.'

'Why do you keep asking?'

'I just bit my lip'
