Honestly it says something about the media literacy of a bunch of people that I've seen a ton of folks not understanding it's a parody and not a true story after that last trailer. I mean they absolutely could not have made it any more blazingly obvious.
-ZacWilliam, Al himself was joking how "Weird Al and Madonna" was now like the third autofill for his name.
In all likelihood Al has had a pretty mundane life aside from the part about being one of the funniest songwriters of all time, which we already knew. If a famous entertainer has a life that's anywhere near as eventful as their career in entertainment, at least 9 times out of 10 it's not for good reasons. I'm... not even sure I can think of an example of the tenth case.
