Who is Mr. Snerdley on the Rush Limbaugh show?

Snerdly is a nickname that Rush made up and gave to his call screeners during the early years of his national show. There were actually several Snerdlys. If I remember correctly, the longest running of these was Bo Snerdly (real name James Golden). In the early days of internet radio, Golden left Rush's show to do his own internet talk show. However, this only lasted for about a year before the company folded up. Since this time Golden has rejoined Rush's support team as the "Official Program Observer". I don't really know what this job entails. Any way, when you here Rush refer to Bo Snerdly or Mr. Snerdly on his show, this is who he is talking about.

Is there anyplace we can see a pic of H.R. Dawn, and Bo?

He is a screener on the radio talk show.

James Golden co-hosted a Sunday night call-in show on WABC (770 AM) in New York during the 1990s. He had a brash sense of humor and a confident delivery. Very much his own style, not in any way reflective of his boss, MahaRushie. His co-host was Joel Santisteban. The show was called James and Joel.
