altDon’t count on Sen. Scott Brown (R-Mass.) for a few chuckles. According to the junior senator, his wife, WJLA reporter Gail Huff, thinks he lacks a funny bone.

Brown appears on the cover of the August issue of the Nantucket-based, N Magazine. When asked whether he’s changed in any way since he was voted into office (in a January 2010 special election to fill the late Edward Kennedy’s Senate seat) Brown said, “Yes, I think I’ve changed. I know that I’m more knowledgeable about a whole host of things…But, my wife says I still am the same guy with a terrible sense of humor.”

But even if he’s labeled unfunny at home, at least Brown seems to be a pretty fit. Brown recently placed fourth in his age group at the Iron Man Triathlon – besting his 2010 time by five minutes.
