My son’s sh*t drawing of a snake.
Explanation: This joke plays on the absurdity of a child’s drawing, humorously describing a snake with “three legs and four arms,” which clearly doesn’t make sense. The punchline relies on the expectation of a literal or unusual creature, but instead, it highlights the humorous inaccuracies often found in children’s artwork. The exaggeration of the drawing’s “flaws” makes it funny and relatable.
