BACK TO SCHOOL. From the "cure worse than the disease" panel, the longstanding controversy over whether or not Pluto (not the dog) should be downgraded from planet to planetoid looks set to be resolved by redefining the word "planet" so as to make Pluto fit the bill. The only problem -- the asteroid Ceres, the far earth orbit object 2003 UB313, and Pluto's moon Charon would all count as planets, too under the new rules. This is reminiscent of nothing so much as the Bush administration's radical 2005 plan to alter time and seems likewise ill-advised.
