I love that article. It tells you everything you need to know about AAAAAAAAAAAAAAAAAAAAAAA.
It helps if you actually imagine the movie, with all the same direction and action, except everyone is screaming at each other. The princess all holed up with R2D2 while the storm troopers swarm their ship. She leans over and screams into R2D2 for a little bit. And then there's the end, when Obi-Wan's spectral voice is screaming AAAAAAAAAA at Luke over the Death Star (or the AAAAAAAAAAAAAAAAA as everyone called it).Classic.
Do it with all of your favorite films if you want to stand there laughing like a lunatic while your friends and family cringe at your apparent spiral into dissociative madness. Or, as they'll eventually start to call it, AAAAAAAAAAAAAAAAAAAAAAAA
