There's two nuns driving down a highway

when all of a sudden satan appears on the bonnet of the car. The nun driving is shocked and says to the nun in the passenger seat, "ahh! what should I do!?" the nun in the passenger seat replies "Show him your cross!". So the nun driving leans out the window and yells "GET OFF MY BONNET YOU FUCKING CUNT!!!!"
