C-Span

I've been watching and listening to C-span most of the day. (I went to one job but it was a lazy day as my government contacts had taken the day off, that's right, "you can't shut us down, we're not coming in anyway")

I have one question: Is it a requirement for participants of the C-span call-in shows to drink to the point of immobility before calling in? (it seems like a month since there's been a sober person on the independents-line from Springfield Missouri.
