The AT-AT is a character in Cosmic Wars: The Gathering Shadow.
He bursts into the galactic senate building to propose an amendment to a Space Bill 371 but is told to wait his turn by the galactic senator, who had been in the middle of a role call. He then sits down and reads the Evening Standard.
Bart Simpson, when watching the movie, was uplifted when he saw the AT-AT burst into the senate, as he believed it would allow him and the rest of the audience to finally see action they were dying to see, although after seeing the exchange and it going back to the role call, Bart and Homer ended up upset and getting bored.
Behind the Laughter
- AT-ATs are vehicles from the Star Wars series. In the films they did not speak because they are simply big mindless vehicles.
