Here are some one liners...
Galileo, Jupiter's Moons and Pluto's New Horizons -- Galileo improves the telescope and discovers 4 moons of Jupiter. I talk about Pluto, it's moons and the fact that Pluto is smaller than all of those 4 moons that Galileo discovered.
Judge Dread is Judged Illegal: Common Law vs. the Parliament -- This is all about judicial review and the fact that the people acting as policemen cannot also act as judge and executioner (or collect fines, etc.) The job of a judge is also to review the law itself.
