Explanation
The Joke
A father tells his son it is time for "the talk." The son says he already knows about sex, so the father pivots: "Good. Let's have the relationship talk instead." What follows is a bleak, realistic lecture about how it is practically impossible to judge a mate at the outset of a relationship, how the things that attract you at first become irrelevant over the long term, how couples subtly mold each other over time, and how initial criteria for partner selection bear little relationship to long-term compatibility. He concludes: "And there's nothing you can do about it."
The son, horrified, says "This is a nightmare. Can we start over and pretend you know more about sex than me?" The father replies with a classic: "That's what she said."
The Humor
The comic subverts the classic "birds and the bees" setup. "The talk" is universally understood to mean the awkward sex-education conversation between parent and child. By having the son already know about sex, the father instead delivers an even more uncomfortable truth: that romantic relationships are fundamentally uncertain, that initial attraction is a poor predictor of long-term happiness, and that there is essentially no reliable way to choose a life partner. This "relationship talk" is far more existentially terrifying than any sex talk could be. The son's plea to go back to the sex talk highlights that frank information about the mechanics of sex is far less disturbing than the philosophical reality that love is largely a matter of luck. The father's closing "That's what she said" joke perfectly caps the comic by undercutting the heavy emotional content with the most juvenile possible punchline.
