C-SPAN is typically one of the less scintillating channels on television. With its near-constant broadcasts of speeches from obscure legislators and of congressional subcommittee hearing after endless congressional subcommittee hearing, it’s often most valuable as a nap soundtrack. But every once in a while, C-SPAN really comes through, like when its hosts interview public figures and journalists and then let Real Americans call in. This happened last week when one caller pretended to be the Fresh Prince of Bel Air. That event was not an aberration. C-SPAN gets weird, a lot. It’s the TV version of Internet comments, and it’s amazing.
