At the end of the show (between SC guy and Paul's call), someone called with a "Simpsons" moment, or something along those lines. Tom said "What is this, the Paul Goebel show?"
I had to look it up, but Tom was referring to this guy:
http://en.wikipedia.org/wiki/Paul_Goebel. I didn't know his name beforehand, but I like knowing that Tom knows his name, and I like that I now know his name, too.
