South Park hits a milestone later this year when it airs its 20th season on Comedy Central, and to celebrate, the show put together this hilarious new ad called “We’ve Been There.†Sometimes it’s easy to forget that South Park has always been there for us since way back in 1997, and thankfully we can count on Trey Parker and Matt Stone to continue being there for us through at least 2019. Season 20 premieres on Comedy Central Wednesday, September 14th at 10:00pm, and in the meantime, the network will air a South Park marathon every Wednesday from 1:00pm to 10:00pm.
