I've been a big fan of Art Bell and Coast to Coast AM for years. I'm a subscriber to their Streamlink thing which lets me listen online. I automagically download podcasts of each night's show. I am positively addicted to these shows where you could have Michio Kaku one night, then psychics the next, and open lines for time travellers and aliens the next. I strongly urge you to check it out if you enjoy High Weirdness of any kind. Trust me, if you're here in the U.S. or Canada, it's on a radio station late at night somewhere near you.
One thing to bear in mind, though, before you call Mr. Bell: he is a veteran of a thousand radio wars. It is not an easy task to mess with his head, as this caller, Oscar, recently learned (MP3 link).
