Some mashups just work. A few of them really, really work. This is an example of the latter.
YouTuber The Unusual Suspect took footage from the original Star Wars trilogy and repackaged it in the style of the first few GotG trailers. It's a little unreal how mimicking the latter's action-packed visual comedy while applying its font and musical choice can add up to this much wonderful. Seriously, I've watched this five or six times now and I can't stop grinning like an idiot.
