These three stories are the kind of twist ending 2 or 4 page stories that 2000AD later popularized as Future Shocks – Alan Moore wrote a fair number of them. It’s interesting that this issue has three of them. The first page (or pages) usually contain the setup and the last page always has the punchline.
