I do feel sorry for the poor Slow Children At Play, however. How humiliating for them.
*giggle* The much-older brother of my best friend in high school had a band by this name. Never failed to piss people off, even when he joked that he and his buddies were the slow children in question.
Did they practice in a building with an Automatic Caution Door? :)
