@Intrepid,
it's funny, i used to listen to howard stern when he was on terrestrial radio, gilbert was a frequent guest, i loved him as a funny guy in general conversation, but not as a straight out comedian
the same goes for a lot of comedians, i now listen to opie and anthony, and they have a lot of comedians sit in as guests and again i find them quite enjoyable in general conversation but when i've looked up their comedy, not so much
