Two women were walking around somewhere in Nevada on a blisteringly-hot sunny day. They were looking for a way to cool off a little. They passed a prostitute eating watermelon on the porch of a whorehouse without any panties on, so they asked her if she was any cooler by not wearing any panties.

The pantyless hooker replied, "Well I don't know if I am any cooler but it sure does keep the flies off my watermelon!"
