IIRC, one of the SP guys has a home in Venice, CA, and wanted to put up a higher privacy fence to block out the bums hassling him and his in his yard. Some aging hippie selectman with a ponytail (named Matt something - the selectman, not the ponytail) blocked the "renovation".
Near the end of the epi, in the rewritten song, the lyrics go something like "...are nice to the homeless/you can hang at Matt's house..."
This should be a rule at FR. If you’re going to site a South Park episode, you must specify the season and episode number so the rest of us can watch it. I don’t watch SP often and almost always on recommendation from someone. I watch it more as I would watch other social commentaries.
