SonicSpike writes: It's hard to believe that Trey Parker and Matt Stone didn't know exactly what they were doing with Wednesday night's season premiere of South Park. This episode marked the beginning of the show's 21st season and as usual, South Park took on current issues like tiki torch-wielding white supremacists and... home digital assistants. The latter meant lots of gags in which Cartman and other characters addressed Amazon Echo's Alexa and Google Home as well. And that ended up being a problem for viewers who own those devices. (Editor's note: example 1, 2) South Park writers absolutely knew their lines would do this and probably had a hilarious time coming up with funny commands for the home assistants.
