Falling apart? Yeah, same here. But we’re holding it together — more or less — and that’s exactly the vibe this shirt delivers.

It’s the perfect fusion of nuclear physics and painfully relatable humor. Because let’s be honest — whether you’re a radioactive isotope or just running on caffeine and denial, this shirt understands you.

Smart, funny, and just the right amount of unstable — kind of like you on finals week.

• 100% combed and ring-spun cotton (Heather colors contain polyester)
• Fabric weight: 4.2 oz./yd.² (142 g/m²)
• Pre-shrunk fabric
• Side-seamed construction
• Shoulder-to-shoulder taping


This product is made especially for you as soon as you place an order, which is why it takes us a bit longer to deliver it to you. Making products on demand instead of in bulk helps reduce overproduction, so thank you for making thoughtful purchasing decisions!
