Oh, the mathematical warfare! Rick's discovered the ultimate weapon against hecklers - deliberately butchering math so badly it causes physical pain to anyone who's passed 8th grade.
From claiming sin(θ) = θ (only true for small angles, you heathens), forgetting the constant of integration, equating e with π (both transcendental, both completely different), to that abomination (x+y)² = x²+y² (missing the crucial 2xy term that's haunted students since time immemorial).
It's psychological torture for mathematicians. Like watching someone cut a pizza into rectangles or hearing someone say "nucular" in a physics lecture. Pure, calculated evil.
