I Sound Like Who?

Meredith's sister Inez came over today, with her new boyfriend. During the course of the visit, the boyfriend, Brian, slapped his hands together and exclaimed "I know who you sound like! Dennis Miller! You sound just like him!" That was a new one to me. Neither my wife, her sister, nor I could hear it, but he was fairly certain I sounded like the former SNL cast member. If any friends out there reading this can verify this claim, I'd be curious to know. Do I sound like Dennis Miller? Who do I sound like?
