You could tell BriWi wanted to say something...he looked like the cat that ate the canary. 

Williams was reporting on a new ranking of popular baby names.

According to NameBerry, Marnie is a newly popular name for girls. Fan of the HBO show 'Girls' will likely know the news anchor’s daughter, Allison Williams, plays Marnie on the show.

“The big activity is among girls. The folks at NameBerry say Marnie is suddenly hot because there is a character named Marnie on an HBO series,” Williams said Friday on NBC’s Nightly News.

Williams didn’t note the character was his daughter, but there seemed to be a slight twinkle in his eye as he reported the news. So, was this report the stolid news anchor's version of the humble brag or Williams' demonstrating he's the consummate professional by not explicitly mentioning his daughter?
