Q. Who supplies the voice of the camel in the new Geico “Hump Day” commercial?

A. The voice heard in the commercial, which likens how happy Geico customers are to how happy a camel is on Wednesday â€" also known as “Hump Day” â€" is provided by Chris Sullivan, according to Theresa Dunn, a spokeswoman at the Martin Agency in Richmond, Va., which is the longtime creative agency for Geico.

Mr. Sullivan is “an actor, voiceover talent and musician with many years of experience in the entertainment industry,” Ms. Dunn writes in an e-mail. In addition to Geico, Mr. Sullivan’s “commercial acting career includes work for Jack Daniel’s, Snickers, Hilton and Budweiser.”

Mr. Sullivan has a personal Web site and a page on IMDb.

Q. This is in reference to the Q. and A. on July 15, before you went on vacation, about a Clorox bleach commercial and a woman’s belief that she heard the child in the spot say, “I’m Mitt Romney.”

I believe that in replying to her, you shared a link to the wrong commercial because what the boy says (“Mommy, I made poo poo”) would be hard to confuse with Mr. Romney’s name. There was, however, another spot for Clorox bleach in which the little boy yells, “Mommy, I went potty.” Although I still don’t hear “Mitt Romney,” I can see how the potential error might happen.

A. Thanks, dear reader, for clearing that up. Although the “potty” spot is no longer available on YouTube, descriptions of it I found on Facebook suggest that it was indeed the Clorox commercial to which the inquiring reader was referring.
