Watch: 'South Park' has Bill Cosby drug Taylor Swift

Yesterday marked the closing of South Park's 18th season, an occasion marked by the airing of a holiday special, "#HappyHolograms," in which embattled comedian Bill Cosby appears alongside pop superstar Taylor Swift. As you can imagine, it only gets worse from there.

The episode itself was not actually about the Cosby sexual assault allegations, instead serving to close a two-part plot that lampoons modern entertainment via a holiday special called "The Washington Redskins' Go F--- Yourself Holiday Special." South Park protagonist Kyle Broflovski joins in at the behest of a hologram version of Bill Cosby, hoping to "#savethelivingroom" and re-establish the dominance of traditional entertainment.

So, yes, it's a little confusing.

Cosby and Swift, however, appear on the "Go F--- Yourself" special to sing a disturbing rendition of "Baby, It's Cold Outside," notoriously one of the creepiest Christmas songs in history.

"Say, what's in this drink?" sings South Park's Swift after Cosby hand's her a glass of wine.

"That's just some J-E-L-L-O," Cosby croons back, intensifying his attempts to get Swift to stick around.

Later, in a scene dubbed over by a conversation between South Park's Eric Cartman and YouTube star PewDiePie, Cosby can be seen encouraging Swift to drink her wine and stay with him. As the scene begins to close, Swift closes her eyes, apparently passing out.

Meanwhile, in real life, Cosby is currently facing a defamation lawsuit via accuser Tamara Green, who claims that the comedian's repeated denials have branded her a liar in the public eye. More than 20 women have accused the comedian of sexual assault. He has never been charged in any of the allegations.

Check out the holiday episode of South Park below. The Cosby bit comes in around 16:34 — but, being as this is South Park, there is foul language, so please, watch at your own discretion:
