Ah, the classic Teletubbies invasion of your codebase! The meme brilliantly shows how synchronous functions (a through e) work together in harmony, holding hands in a neat little circle. But then that one async function shows up and BOOM – suddenly your clean execution flow is replaced by an army of purple creatures taking over everything. This is basically what happens when you introduce that first async function into your previously synchronous paradise. One minute you're writing nice, predictable code where everything happens in order. The next minute you're dealing with promises, callbacks, race conditions, and wondering why your console is printing results in what seems like a completely random order. And just like Teletubbies, once async enters your codebase, it multiplies uncontrollably until your entire project is saying "Eh-oh" to debugging sanity.
