My source says...
Talk show host #1 isn't as chipper as her persona, but she's not necessarily a raving loon. Once her orders come down the chain of command, she does sound demanding. Hard to say if that's from her or the others along the way.
Talk show host #2 is a loon, a nut, and all around completely crazy.
Talk show host #3 is new at this gig, but not showbiz, and she is nice.
Talk show host #4 is same as #3 but male.
None are Opie!
