Sometimes the political commentary in episodes of the Simpsons TV cartoon show is fairly sharp. Not so with tonight's 20th season finale episode written by Brendan Hay called "Coming to Homerica", which wasn't more than a hamfisted harangue in support of illegal immigration. It featured Norwegians (i.e., Mexicans) from Ogdenville who emigrated en masse to Springfield and ended up doing jobs such as roofing.
