The canned/tinned mystery
meat that appeared in the movie Waterworld.
Society is so FUBAR in that movie, that the
people actually look forward to being able to eat it.
The makers of Spam must have known that Waterworld was going to be box
office poison, because they didn't even want the product placement/endorsement. The movie producers ended up using a cheesy
rip-off called "Smeat" instead.
In a time of celebration, Dennis
Hopper's character threw cans of Smeat to his crew - and, strangely enough, they didn't run for their lives.
