We've had several posts recently (here and here) showcasing the humorous consequences of interpreting quantifiers overly literally, with a blind eye to the usual contextual limits on their domain of interpretation. The following comic illustrates another possible pragmatic failure when it comes to quantifiers:
This time, the failure is not in domain restriction of course, but in failing to acknowledge the intended communicative force of the question. Instead of taking the server's question to be something akin to "Addressing myself to each of you, what do you want from the bar?" the logicians interpret it literally and uncooperatively as a yes/no question—the answer to which only the last of them is in a position to deduce based on the answers given by the other two. By the way, if you've ever gone to a bar with a logician, you know that they are likely to engage in just this sort of behavior as a form of tickling themselves.
(I found this comic thanks to Peter Lasersohn; it comes from the folks at Spiked Math Comics.)
