As a Catholic, you might like this one:
A priest was driving along and saw a nun on the
road side. He stopped and offered her a lift which she
accepted. She got in and crossed her legs, forcing the
habit to open and reveal a leg. The priest looks and
nearly has an accident.
After changing gear his hand slides up her leg. She
immediately says, "Father remember psalm 129?" The
priest apologises profusely and removes his hand but
is unable to remove his eyes from her leg.
Further on, he changes gear and has ogled at her leg
for the zillionth time his hand slides up the leg
again. The Nun once again says "Father remember psalm
129?" Once again the priest apologises "Sorry sister,
you know the flesh is weak."
Arriving at the convent the nun gets out and the
priest goes on his way. Once he arrives at his church
he rushes to the bible and looks up psalm 129
it said:
"GO FORTH AND SEEK, FURTHER UP YOU WILL FIND
GLORY"
