Here's a joke I heard, which is based on a classic ethnic jibe:
Guy goes to the doctor for his annual physical, and the doctor concludes grimly "brain tumor". It's a terminal diagnosis, and the guy is gnashing and wailing and pleading with the doc for any sort of good news.
The doc says, "Well, we could let you into an experimental program performing brain transplants. I warn you though - it's expensive."
"Anything! Anything! I'll pay any price!"
The doc informed him that two brains were currently available for transplant - one was from a recently deceased Jewish fellow and would cost $2,000. The other available brain the doc didn't have much information about other than that it had belonged to a Donald Trump supporter. The cost - $100,000.
"$100,000??!!! Why so expensive?", asked the man.
The doc replied, "Well, it's almost completely unused!"
