"Bob" does not really exist. It did create protests for the on-air humour and anti-religious comments. There is no Church of the Sub-Genius, there is no nothing but satire and humour not for the weak-minded and easily offended. Just the best radio (almost TV via MTV) show/farse I ever heard.
I learned about bands like Morphine (a extremely unique 3-piece band from Boston, USA that are dark and not "over-dubbed") and Einstein's Secret Orchestra (there isn't anything they can't play).
There are some graphics not suitable for children regarding the "Devival". This is a spoof of the "revival" that religious factions hold.
It's anti-everything and even has 10 minute marriages that you can get from the "church" and terminate thus after the 10 minutes is over.
OK, I'll stop now.
