Lena Dunham is back promoting her 'life in Brooklyn' documentary series Girls, as the final season of the series kicks off on HBO this Sunday, February 12th. During her appearance on the Today show this morning, she brought things to a pretty PG level for morningtime viewers, using the word "penis" during her interview with Maria Shriver. Despite "penis" being a scientific term, it completely threw Shriver off, launched her into a giggle fit, and caused her to completely malfunction for what seemed like a lifetime on live television. Someone please Curb this for us:
