There's a series of public service announcements about how important it is to take your kids to listen to classical music and see fine art. They have lame puns about a diet of Raisin Brahms and Van Goghgurt. "Kids who go to the arts get better test scores," they say. Gee, I wonder if that's caused by exposure to the arts (well, maybe, if the tests are about the arts in question), or if the exposure to the arts and the better test scores are both effects of something else.
Anyway, the ads drive me crazy. That is all.
