When you order a drink, they bring it to you with a bar napkin. Each paper napkin has a different nautical cartoon/joke on it. They're never funny, but the one I got last time was egregiously bad.
First, it's not even a joke. Not remotely so.
Second, the answer (upside-down at the bottom) is also written on the blackboard — thus giving away the punchline.
Which is not a punchline.
Because it's not a joke.
Is the person who made this on drugs? Is he insane?
