The parish priest needs his house painted so he offers the job to one of his altar boys. The first day the kid paints the entire inside of the house, he's sweating like hell but eventually gets it finished. The priest commends him on the work and with a flourish hands him 50p. The boy looks at the coin and says to the priest, "Thanks very much Father, you're a virgin".
The priest is a bit startled but makes no remark. Next day the boy has to paint the outside of the house; it's a really hot day and he just manages to finish the job without collapsing. The priest looks at the job and this time gives the lad a pound coin. Once again the lad looks at the coin and says, "Thanks very much Father, you really are a virgin".
At this stage the priest decides to take action. "Tommy," he says, "that's twice you called me a virgin. Do you have any idea what the word means?"
"Yes" says the brat, "a tight c*nt."
