yeah its a little hard to believe but Ive seen it happen before, professional broadcasters dont acknowledge the caller is speaking and just move on as if nothing happened. I cant find anything about this being fake, but it seems to date back to 2004. here's a compilation of cspan getting pranked, http://digg.com/lbv.php?id=2363884&ord=1 pretty funny bc they do get to the broadcasters although I think a few of them are stern fans
im not sure how it works but they are always really slow to drop callers. i think the host themselves have the buttons.
i never understood why they dont have a dump system on cspan. its the reason why people keep doing that.
the best part and why i used to watch the morning show with callers was you would get perfectly normal politicians and experts and then some racist fucking loon would call in and just go off on conspiracies and jews. and the host would just uncomfortably squirm and sit there listening to it all. they only hang up on alot of cursing. other then that they have to let all the calls through. its funny shit.
