So I was doing novel research.
Basically, when you see "Something Walmart this way comes" in Wikipedia's See Also section, you click.
Turns out, it was a South Park episode.

Soon, the now-unemployed residents start to work at Wall-Mart for minimum wage and an extra 10% employee discount on store purchases, including Stan's father Randy.

That's either a grammatical error, or an episode I would really like to see.

Love always,
