Sulphuric Jokes

Little Johnny was sitting outside a church playing with sulphuric acid.
The priest came up to him and said "Child why are you playing with sulphuric acid? Thats dangerous! I've got some holy water inside that is much more powerful."
Little Johnny relied "How come?"
"Well last week I splashed some holy water on Mrs.Wilson's tummy and she passed a baby!" said the priest proudly.
"Thats nothing," retorted Little Johnny "I spashed some sulphuric acid on my dog's balls and he passed a Ferrari!"
