Come Back
Explanation
The Joke
A wife tells her husband to come to bed, but he insists he can't because he has to argue with "an internet guy about historical economics." She points out that he doesn't know anything about historical economics, to which he gleefully responds, "It's okay, neither does he. We can go all night long."
The comic captures the essence of online arguments: two people with zero expertise on a subject can sustain an endless debate precisely because neither one knows enough to actually resolve the disagreement. The phrase "we can go all night long" — typically a romantic boast — is repurposed here to describe the stamina of internet arguers, making it clear where this man's real passion lies.
The Humor
The punchline works because it reframes ignorance as an asset rather than a liability. In a normal argument, at least one knowledgeable party could end the debate with facts. But when both participants are equally uninformed, there's no natural stopping point — every claim can be met with an equally baseless counterclaim. The husband's excited expression in the final panel, combined with the romantic double-entendre of "all night long," perfectly captures the addictive thrill of pointless internet debates. The wife's resigned expression completes the joke: she's essentially been rejected in favor of a stranger on the internet.
