I bought a pack of Death Cigarettes back in the 90s just to have an example of truth in advertising. They remain unopened, sitting on a shelf next to my skull playing cards. The cards really missed the boat, not having the face cards be skull faces.

I'm watching episodes of Space 1999 now to prepare for the upcoming RPG that my friends and I are going to play, and they do a similar thing as part of the opening credits. It's a quick montage of scenes with the groovy Space 1999 music, and they occaionally flash up the words 'This Episode'.

This one is a pretty strong contender.
