Little Johnny was playing with something in the road. The local vicar came up to him and said "Hello little Johnny whats that your playing with?"
Little Johnny replied "It`s Sulphuric Acid"
"You mustn't play with that," gasped the vicar "it's dangerous"
Little Johhny says "Hey, I don't tell you not to play with holy water!"
Vicar says "No, because holy water is good. The other day I put holy water on a
pregnant woman's tummy and she passed a baby boy."
"Well..." says little Johnny "...the other day I put Sulphuric Acid on my dogs Bollocks and he passed a Ferrari"
