Joke Poo

I asked my German friend if he knew the square root of 81

Posted on September 21, 2025 by Joke Poo

He said no

Okay, here’s my attempt at a “Joke Poo” of your joke, keeping the core “misunderstanding of the question” element:

Joke Poo: The Geology Exam

I asked the geology student if he could identify the composition of the metamorphic rock gneiss.

He said, “No, schist I can’t.”

Alright, let’s break down this comedic gem.

Joke Dissection:

  • Setup: “I asked my German friend if he knew the square root of 81.” This sets the expectation for a math-related answer.
  • Punchline: “He said no.” This is a classic subversion of expectation. We expect a mathematical answer (9), but instead, we get a denial of knowledge. The humor comes from the unexpected, seemingly dismissive response.
  • Humor Element: The joke relies on a stereotype (whether intentional or unintentional) that Germans are very intelligent and knowledgeable. The fact that the German friend doesn’t know the simple answer is the punchline. The humour also comes from the ambiguity. Does he not know, or is he refusing to answer to be difficult?

Key Elements:

  1. Square Root of 81: A basic mathematical concept.
  2. German Stereotype: Implied association of Germans with intelligence and knowledge.
  3. Subversion of Expectation: The surprising, non-mathematical answer.

New Piece of Humor – “Did You Know?” (Based on Element 1: Square Root of 81):

Original Joke: I asked my German friend if he knew the square root of 81. He said no.

New Humour:
Did you know that the square root symbol (√) is actually a stylized lowercase “r” for “radix,” which is Latin for “root”? So, technically, when asking about the square root of 81, you’re just asking for the root of 81, which, depending on your German friend’s mood, could mean he’s unsure about the roots of his identity and therefore cannot provide an answer about the square root of 81. Perhaps the real square root was the friends we made along the way.
