At first I wasn't totally convinced this was 100% comedy-related, but then I remembered: cartoon themes are inherently ridiculous. Not only do they have to be catchy and memorable. The best also incorporate amazing harmonies and unnecessary key changes, all while summarizing a show's often-complicated premise in less than a minute. Hence, lyrics brimming with insanity and inanity.
So thank you, folks-at-Cracked, for compiling an excellent list of those old unforgettable cartoon songs of yore. And though I somewhat disagree with the order, the list is quite comprehensive. Almost.
