In the movie Futurama Bender's Big score there is a scene about 11.5 minutes in, where everyone has just downloaded the scammer virus and the Professor is telling them off. In the wide-shot, on top of the bookshelf in the right-hand corner is the frozen corpse of Seymour Asses, Fry's beloved dog.

This is very significant because the movie gives a lot of resolution as to what happened with Seymour all those years ago...
