H.R. Pufnstuff and Mr. Hankey the Christmas Poo

I was bored looking on netflix this a.m. and I came across H.R. Pufnstuff. Its been a while since I watched the trippy a$$ show. I put it on and one thing I couldn't help but notice was that the talking flute sounded and acted just like Mr. Hankey the Christmas Poo. Trey and Matt had to have gotten the idea from the flute. There is no way possible it couldnt be. My wife hates South Park but she even said they were the same character. Check it out and let me know what you think.
