Hidden in a background shot of the latest Star Wars: Clone Wars episode (season 5, episode 12) as an Easter Egg are these three rather familiar looking posters. This was the 100th episode of the animated show.

Thanks to mixnmojo lurker Join the Schwarz for the heads-up.
Update: Join the Schwarz says that the Aurebesh text on the posters read "Kowakian Monkey Island", "Full Throttle" and "Day of the Sarlacc".
