As someone who grew up during the peak era of Nickelodeon, whenever I come across a funny meme that rides a wave of nostalgia, it takes me right back. It’s like suddenly, I’m in my living room, cereal in hand, wondering if slime feels as gross as it looks. And honestly, who needs a time machine when you have 90s cartoons? Each funny Nickelodeon meme is a trip – and not always the kind you need a permission slip for.
