We all overindulged on some Nickelodeon growing up. It was the cool thing to do after school: veg out while watching cartoons like Rugrats, Rocko's Modern Life, and CatDog.

Now Johnny Cupcakes has immortalized those familiar characters by collaborating with Nickelodeon for a limited edition batch of T-shirts commemorating cartoons from our childhood like Ren & Stimpy and Spongebob Squarepants. The brand masterfully combines the memorable characters with his very own cupcake designs.

The tees are now available online for $40, but they are running out fast. So hurry if you're still not ready to fully become an adult. It can join another childhood favorite; the new Stussy Beavis & Butt-head collection. [Johnny Cupcakes]
