Episode 2 of Season 4 didn't do quite the numbers it did last week (1.142 million this week, 1.232 million last week), but keeping in mind it's normal competition on Thursday nights PLUS the new season premiere of "It's Always Sunny" on FX last night, it's still not too shabby :)
Anyway, here is the answer to WHERE OTHER CREW MEMBERS "DISAPPEARED" TO (I've been seeing it a lot lately) - no one was fired/let go of/gotten rid of. filming schedules for the show are sporadic. crew can't always drop everything in their lives and film for a few months. Josh and the production company folks can focus on it full time, but the other crew members take other projects.
I'd also like to let you know that I have more "DT Fan Radio" shows coming up, including a BIG show I'm planning with Ryder & Josh in the first week of October. Air date & details coming soon! I am also working on the first funniest moments video of Season 4 and other fun stuff. Stay tuned :)
