Hidden Message in South Park CD track

[♩♬🐸 Billy C ♯♫♩🐇]

So, I was trying to find something to sample for this track I'm working on, and I decided to sample part of the South Park Christmas album, and reverse it. I did so, and was astounded by what I heard in the playback. I copy & pasted that, and uploaded it here. I put the version as it appears on the cd, first, and then put the reversed part. I found this entirely by accident; I promise I did not do anything to 'alter' the sound in any way. What I don't get is why Trey Parker put this in there, as who in there right mind would think to play this part in reverse?

What exactly is it that I'm supposed to be hearing?

Check out 31-35 seconds in. Please don't grow up and marry that n*****?   I'd laugh, but I'd go to hell for it.




Nah...I'm going already.    

Edit: I just wanted to clear up any possible confusion about my comment. As for my "I'd laugh, but I'd go to hell for it" comment...well, have you ever been in a situation where you thought something was funny, but at the same time it wasn't? I found the odd "randomness" of the "message" funny, not what was actually said.
