I tend to stay away from blonde jokes, for the same reason I stay away from “pollock” jokes. However, jokes about stupid people jokes are really funny, if only we could suck out the pejorative. So call [this](http://brandywinebooks.blogspot.com/2006_01_01_brandywinebooks_archive.html#113708696234580261) a “stupid person” joke and we’ll all be fine.
It’s still pretty funny.
