Well, I think it's a safe bet to say that Jason Dohring will not be getting the billing he should (ie, right after KB). Why? Because of the DVD case that the 1/2 S3 eps that were sent out.
Check it out: DVD box
It reads: Kristen Bell, Enrico Colantoni, Percy Daggs III, Jason Dohring ...
Sorry, it pisses me off. The guy is in all the episodes and IS the male lead on the show (yes, moreso than EC now) and he still gets billing after a guy who isn't even in all the episodes. Grrrr.
