'South Park' Takes on Bill Cosby ... Baby There's an Assault Outside

12/11/2014 10:50 AM PST

"South Park" took a slightly-pervy sounding Christmas song, infused the Bill Cosby allegations, and the result was a little creepy and kinda funny.

A hologram-version of Cosby attempts to keep Taylor Swift in his home by singing "Baby It's Cold Outside" ... and eventually holo-Cos offers her a drink ... just like many of his accusers say he did to them. 

Later in the episode, Cosby and Swift are seen getting closer -- but, as you can imagine, it's totally a one-sided affair.

Check out the clip ... there's even a Jell-O reference. A rapey one, but it's there.
