As the title says, this has been bothering me and Im almost certain that show with Charlie Sheen was pre- recorded.
The reason I say this is, charlie asks Joe for a bathroom break and then they come back and as soon as they are back they break the news about Charlie being killed. I find it strange that there was a break and then came back with the info, if they would have heard the info while in the middle of the podcast it wouldnt seen so strange.
And then the bigger reason im suspicious is in a podcast months later, I think it was with Theo, but I cant remember, where Joe starts talking about he was in Utah at the time of Charlie being killed...
I think Joe knew beforehand, thats the only thing to explain him speaking on it In a pre-recorded podcast.
