Background: in the House, if a representative makes remarks during a debate that another representative finds inappropriate, that representative may move to have the speaker's "words taken down". The transcriptionist reads the statements back to the chair, and if the chair determines believes the statements to be inappropriate, then the speaker must step down and is not allowed to speak for the rest of the day without special permission.
More background: The smiley old guy you see at one point is a representative from Oregon. The reason the chair recognizes him is because he was allowing Weiner to speak on his behalf (i.e., Weiner is speaking during the time allotted for the Oregon rep).
Trivia: Jon Stewart and Anthony Weiner are old friends. Stewart's roommate was Weiner's girlfriend back in the day, and Weiner practically lived with Stewart during that time.
