Explanation
This comic satirizes the stereotype of economists reducing all human interaction to transactional, monetary terms. In the first panel, a man at a bar tries to make conversation, noting that economists are "obsessed with money" even though "they don't feel it." He suggests that if you introduced money into ordinary social situations, it would make them "feel executive."
In the second and third panels, the conversation takes a sharp turn. His preference for "interesting conversation" is immediately quantified: "a 3-minute conversation is worth 12 dollars to you." The final panel shows someone calculating the running total: "you've been talking for 8 minutes -- that's 32 dollars."
The humor comes from the instant, involuntary way the economist (or economics-minded person) converts a casual social interaction into a cost-benefit analysis. The man's own complaint about economists being obsessed with money gets immediately proved correct by the response he receives. It also plays on the economics concept of revealed preferences and opportunity cost -- the idea that your time always has a dollar value, and any social interaction can be modeled as a transaction, whether you want it to be or not.
