Ventura is hilarious, and his show often does contain the occasional fact, but as many have said, to make it really outrageous it has to be manipulated. I saw one episode where he was investigating some kind of compound that apparently had people in it, and he used a tactic that he resorts to WAY too often, that is demanding answers he has no right to receive, then stating the lack of answers as proof of whatever wacky thing he is asserting.
The "west of the rockies" show being discussed earlier is called "Coast to Coast" and is available on my local talk radio station and is also streamed online on their website on weeknights, just look for 610 CKTB. I starts at 10 PM EST I believe, but that is just a rerun of the second half of the previous nights show. The "current" episode starts at midnight EST. The show is good background for late-night internet goofery- as someone(Eaglesmack I think maybe) stated, George Nori (sp?) really does work his guests and callers real well, especially the alien/crypto sighting-types- he knows how to whip things right up, but he does so in a non-patronizing way that makes it almost funny most of the time.
