On Monday night on CBS, millions of loyal “How I Met Your Mother” viewers were rewarded with the answer to a question that they have pondered for eight seasons: Who is the mother? In the final scene of the episode, it was revealed, when Chuck Tatham moved out of the way, that the mother was the Tony-nominated Broadway star Cristin Milioti.

It was certainly exciting to find out who the mother is, but, more to the point, who is Chuck Tatham?

Chuck Tatham is a gifted, humble writer-producer on “How I Met Your Mother.”

Chuck was onscreen for less than a second, but this was a crucial role. How did he get the part?

Chuck assumed he was awarded the role because he’s telegenic and radiates charm. Chuck has since learned that he was chosen because he has a physique like Lurch, and thus effectively hid Ms. Milioti until the reveal.

Why didn’t Chuck have any dialogue?

God knows. Chuck wrote himself pages of clever witticisms, none of which were used.

Did Chuck’s character have a backstory?

Yes. The scene was at the ticket booth of a New York train station, so Chuck imagined himself a weary urologist, heading home to New Canaan after a long day of saving lives at the Mount Sinai Medical Center. But when it was decided that Chuck would receive a map from the ticket taker, it seemed illogical to Chuck that a commuter urologist who takes the train every day would need a map. The consummate professional, Chuck quickly transformed his character into a disoriented drifter, a fact that is obvious from his performance.

How long was Chuck in makeup?

Chuck did not wear makeup. However, as the shoot progressed and Chuck began to sweat like Sarah Palin at a spelling bee, the makeup people repeatedly wiped his face.

What about Chuck’s hair? Who was his stylist?

Chuck’s hair was not styled. In fact, unaware that he was going to appear on national television in a scene that will be replayed on the Internet for the rest of time, Chuck cut his own bangs two days before the shoot because he didn’t have time to go to Supercuts.

Is there any trivia we should know about Chuck’s performance?

Trivia Tidbit No. 1: Chuck wore his own brown Brooks Brothers coat in the scene. Brooks Brothers is known for quality clothing and generosity toward people who mention Brooks Brothers favorably in a newspaper article.

Trivia Tidbit No. 2: Chuck wears a size 46 tall jacket and needs socks.

Where does Chuck Tatham’s acting career go from here?

The sky’s the limit. But Chuck wants the entertainment community to know that he offers a lot more than merely being a big guy who can move out of the way and reveal people. Chuck can also reveal art work, furniture, pets, the Chrysler Building—whatever the role requires.

Now that he’s a star, will Chuck make himself available to the press?

No. Chuck Tatham is not in the business of self-promotion.
