The Old Nun

An old nun who was living in a convent next to a construction site noticed the coarse language of the workers and decided to spend some time with them to correct their ways.
She decided she would take her lunch, sit with the workers and talk with them.
She put her sandwich in a brown bag and walked over to the spot where the men were eating. She walked up to the group and with a big smile said:
"And do you men know Jesus Christ?"
They shook their heads and looked at each other very confused. One of the workers looked up into the steelworks and yelled out,
"Anybody up there know Jesus Christ?"
One of the tradesmen yelled down 'why'?
The worker yelled back, "Cos his wife's here with his lunch"
