I created a short little overdub from the original series. its 100% comedy so don't expect seriousness, also a bit of mature humor. Star Trek: "Who's doing who" Does anyone have anymore links to overdubs like this one. preferably a minute or longer, because i have scene a few real short fart joke ones and those got old fast.
