This is the ultimate Libertarian sex fantasy, compliments of the great Daniel J. Mitchell of the International Liberty website:
On the way home (an extreme libertarian) stopped at the gas station where a drop-dead gorgeous blonde was filling up her car at the next pump.
She looked at the ammo in the back of his pickup truck and said in a very sexy voice, “I’m a big believer in barter. Would you be interested in trading sex for ammo?”
He thought a few seconds and asked, “What kinda ammo ya got?”
