Yeah I agree it was a bit eh, but the more I thought about it (the whole "change is scary" also relating to Dan Harmon and everything) the less eh I felt about it. It still wasn't a brilliant episode (humour felt rather forced at times) but I think Dean made up for it :P
The L&O episode was all sorts of amazing. My favourite part was probably seeing the actual medical examiner turn up as a Biology examiner. So, so good!
It's probably better if you just suggest one to me. I've been doing this for about a year now, so I can't remember offhand every avatar I've had. But if you tell me one I've done before, I'll probably remember. Just be aware that I've got a long-ass waiting list (about three months).
