Squeezing Lemons for forgiveness

There once was a Nun who went to Confession. Upon entering the confessional, she said, 'Forgive me, Father, for I have sinned.'
The priest said, 'Confess your sins and be forgiven.'

The young Nun said, 'Last night a man made mad passionate love to me seven times.'

The priest thought long and hard and then said, 'Squeeze seven lemons into a glass and then drink the juice.'

The Nun asked, 'Will this cleanse me of my sins?'

The priest said, 'No, but it will wipe that stupid smile off of your face.'
