Jack and the Flying Prince and Princess (season 4)

The planet Lepidtopera is under attack from the Squoomians.  The king sends his son and daughter to get their fleet, as his children are now "their only hope."  Their ship ends up damaged, and they crash on Earth. Prince Astor and Princess Verbina have a bad feeling about this.  The gravity hinders them, and they get captured and brought to Darth Aku.  Jack rescues them, and battles a bunch of drones while the kids fix the ship.  They save him from the drones, and go find the fleet to save their planet.

Those are only two of the many Star Wars references in this episode.  The previous episode had one or two as well, but this whole episode was an homage to the franchise.  It was a lot of fun, and told the whole story in 22 minutes or so.  I am quite enjoying this season, and look forward to the next and last season.  Aku and Jack have almost become frenemies by now (they had a duel which was hilarious) in a previous episode.
