Yeah, it's a dupe, but this is the first Good Quality version of this I've ever seen. All the others seem to be hand held cameras held across the room with the volume way down.
This has been duped over and over. In fact the very first comment on the last dupe is some complete 'imbecile' justifying the dupe by saying "at least this one is a better quality video."
I didn't realize this had been duped, and halfway expected to get a never ending string of this video in continuingly degraded versions once I went to the third video. Five for that.
