They used to do this every once in awhile on their old show. It started when they were doing a phone interview w/ Ted Nugent and he volunteered. They had a guy dump a mag in an f/a uzi once.
Except for the blantant sexual content of the show, Anthony actually seems very conservative, (hmmm.... although probably liberatarian fits better) and took pretty much every available oportunity to bash liberals. He's talked about RKBA positively in the past. The others seemed to go along with it, for the most part, although I suspect have more liberal tendancies.
As for the show - it was alright... Definitely took the Howard Stern concept to the next level, for better or for worse. Frankly, I don't think either O&A or Howard will do as well on satellite. Part of either show's appeal is the "I can't believe they said that on the radio!" factor, which will no longer really apply.
