"Souped Up Lincoln" joke

This rich guy from the north is driving his Lincoln Continental down
to New Orleans. Along the way he picks up a redneck.

The redneck looks quizzically at the dash board and says, "What are
those thangs?" The driver says, "Those are golf tees".

The redneck asks, "What those are for?" The driver says "Those hold
my balls when I drive."

The redneck says, "Sheeit, these Lincolns sure come with
everythang!"
