DNA Productions - Hi i'm Paul, No I'm Paul (Lost Youtube Parody)

DNA Productions was a Production company from many Nickelodeon shows, I remember a Youtube video released I believe in 2007 And was posted by a channel called PAUL (I believe it was all upper-cased,) Now I can't find it anymore, I remember watching it back in 2016 or something like that.

The video
It started normally until after Paul says "Hi I'm Paul!" Either a live-action human or another monkey said: "No, I'm Paul."
