Clever biology tee with 'I Run On Coffee & The Krebs Cycle' in bold retro lettering and coffee cup icon. Perfect for science students and biochemistry humor lovers.
The story behind this design
This design plays on the classic 'I Run On Coffee' joke by adding the Krebs Cycle—the actual biochemical process that generates cellular energy. Bold, chunky retro lettering in white and orange sits inside a circular badge design on black cotton, with a steaming coffee cup icon integrated into the text. The whole thing has a vintage sports or energy-drink vibe, making science feel cool and self-aware. It's witty without being try-hard, blending genuine biochemistry knowledge with accessible humor. The design works as both a conversation starter and a quiet wink to anyone who knows why the joke actually lands.
Who it's for
Bio students, chemists, science nerds, and anyone who appreciates smart humor will love this. It's perfect for the friend studying biochemistry or microbiology, ideal for lab coats and lecture halls, and great for anyone who likes their jokes grounded in actual knowledge. Give this to the science major, the coffee addict with a degree, or anyone who thinks scientific knowledge is genuinely funny.
