There's nothing more thrilling than when a science fiction or fantasy series gives a shout-out to longtime fans or includes a fan-favorite character or plot device. But this can be overdone. And sometimes fan-service goes too far. What's the most shameless attempt to cater to fan nostalgia?

Please include a picture, poster, clip, book cover, comics panel or other visual representation for your egregious moment of pandering. And please mention the name of the series, the way that it made a bid for nostalgia, and why it was notably shameless. And please play nice!
