Who would ever think of using the muddy surface of a parked car as a perverse thought bubble for everyone to read? It really doesnt matter who wrote this, as it reflects the twisted creative in all of us. This one drove home (pun intended) two crystal clear points:

2) TO DIRTY GOLF VANDALĀ - You might want to use your finger for similarly creative maneuverings. Perhaps then your wife would eventually be as dirty.
