From Adventure Comics #365, where questions abound:
As a reader noted in last Thursday's post (hey, are you all reading ahead? Stop that!), the 30th Century version of a minority is blue. There still isn't a "Negro" (their term, not mine) to be seen. Why the glass ceiling broke in the Legion for blue people before black people, I have no idea.
I also have no idea why Karate Kid started speaking like Jonah Hex in that issue.
Nor do I understand why the smartest guy in the Legion started drinking water on an alien planet prior to testing it. I mean, you aren't supposed to drink the treated water in Mexico, so I can't imagine drinking water in a stagnant pond on a completely different planet as being a good idea.
You shouldn't always do what the smart guy does, because really smart people have been known to do really stupid things. I believe it is because smart people assume there is only a limited supply of intelligence in a room, and since they are obviously sucking it all up, everyone else must be a moron. But trust me, when everyone in the Legion gets the trots from swallowing a water-borne parasite, Brainiac 5 won't be looking half as smart as he thinks he is.
