St. John Puns

My brother drives for St John's ambulance service and had just dropped a patient in hospital when he came out with this corker..

Nurse: So what's the patients name?

Brother: Ron

Nurse: That's the second Ron we've had in today

Brother: Well you know what they say, 2 Rons don't make a right

Me: did you know that the St. John's is one of two rivers in the world to flow north the other one is the Nile.

Dad: I thought denial was when you didn't admit to something.

Me: groans on groans on groans
