A fellow was dating a girl and the first time he went
to her parents home she took him into the den where
all her father's hunting trophies were displayed.
There were deer antlers and bear heads all over the
walls. The fellow said "Your father must be quite a
hunter!" Then he said "What are those 2 round white
things on the mantle?"

She said "Those are daddy's golf balls".

About a week later the fellow was at her house again
and he saw 4 round white things on the mantle, and
said "I see your daddy must have shot another golf".
