D3 Gag Dubs/Gag Subs/commentary

Has anyone ever tried these? You can take any episode or scene from D3, watch it silently, go wild over what they could be saying, and then add subtitles or record your voices over them. Otherwise, you can simply add your own voice doing some wild commentary over what's happening. It can make for some rather hilarious viewing. You can either try it with friends/fans in a room, or record your subtitles or voices on YouTube/Veoh/Vimeo/whoever allows it.
