The new house maid

The mistress of an English manor had just hired a new house maid,
an Irish lass, straight out of the country.
The first day she was dusting in the Smoking room
where the Master ofthe house sat reading.
On the mantel, she saw and dusted a small bowl containing
a couple of small round white balls.
She, being curious and not bashful, asked,
"What are these?"
He looked up, saw where she was pointing, and answered,
"Golf balls."
She said, "OH!", and went on dusting.
A few days later, she was dusting again in the same room,
where the master was again reading.
Again, in the same bowl were small white balls,
only now there were four.
She said,
"I see you shot another Golf."
