"Hooker Progress" joke

Three generations of hookers were sitting around the brothel one day
just talking about the business. The youngest one complained, "You
know Mom and Grandma, now guys want a blow job and a fuck for $100! I
don't think I can stay in business at those prices."
Her Mom thinks for a while and says, "Well dear, in my day we would
give a blow job and for only $25 and we considered ourselves lucky to
get that!"
Grandma looks at her daughter and her grandaughter and says, "The
both of you don't know what tough times really are. Back during the
depression we used to give blow jobs for free because we were just
glad to get something warm in our stomachs!"
