Irrationally Delicious – Pi Riddle T-Shirt
Some jokes are timeless. Some numbers are endless.
This bold, two-sided design is a playful nod to mathematics lovers and puzzle thinkers. The front poses the riddle — “I’m irrational, but I’m served in slices. What am I?” — paired with a warm, illustrated pie graphic that draws people in. Turn around, and the answer is revealed with confidence: π (3.14159…), served just the way mathematicians like it.
Printed on a premium unisex tee with a comfortable, everyday fit, this shirt is perfect for math enthusiasts, engineers, students, teachers, and anyone who enjoys smart humour done right. Eye-catching, conversation-starting, and effortlessly wearable.
If you like your humour logical, irrational, and well-designed — this one’s for you.
