Johnny Vodka
The Abominable Scotsman
I tried listening to one on Saturday. Opened with 7 full minutes of ads. Then he was waffling on, getting donkies and muels mixed up, with a comedian I've never heard of. Not so bad the last bit there are loads of course but not many lols in the bit I heard. And it was 2 hours long.
I might check out some of the more noteable ones.
If you're interested in psychedelic science, try the Michael Pollan one. That came recommended to me by a friend, after I read MP's book on the subject. MP is such a good speaker.
