Baby Looney Tunes is the early 2000s animated series that reimagined classic Looney Tunes characters as babies, with softer voices, bright colors and gentle slapstick. Short cartoon noises from that style of show became popular online as clean censor sounds because they signal a bleep without using the flat electronic tone from television. Editors began dropping this squeak over dialogue in memes, gameplay clips and reposted cartoons, and it stuck because viewers recognize the joke instantly even without seeing the original scene or knowing the exact episode it came from.
