This T-Rex is killing it with mathematical pickup lines! First, he claims his girlfriend is √-100, which in math terms is 10i (where i is the imaginary unit). Then he delivers the punchline: "She's a perfect 10 but imaginary" – because imaginary numbers aren't "real" in the mathematical sense. The final panel wraps it up beautifully with "Our Relationship is Complex" – a triple entendre since complex numbers contain both real and imaginary parts, relationships can be complicated, and clearly this dinosaur's dating life exists purely in his head. Even the dinosaur audience looks thoroughly unimpressed with his mathematical dad jokes. Poor T-Rex, crushing calculus but not crushing the dating scene!
