I'm A Joke

Hey, listen up, smarty pants! This is like, a classic "Knock Knock" thing, right? The dude on the other side is supposed to say, "I'm who?" And then you bust out the punchline, which uses "I'm" to make a funny name or something. But get this: in this joke, the punchline is just "I'm a joke!" It's funny because it's unexpected and self-aware, which is like, peak humor for dummies like you. Also, you probably watch Rick and Morty.
