Old joke, but on topic.

A professor asks a class if anyone there would be a sex worker if they were paid $1 billion for a year. Everyone raises their hand.

He then asks if anyone in the class would do sex work for one night if the pay was $5.00?

Class is all irate. “What kind of people do you think we are?”

“I know what kind of people you are. Now we’re discussing the prices.”
