Capitol Hill has been described as being populated by only the very old and the very young: Mature members of Congress are often staffed by people in their 20s and 30s, and there is a visible absence of mid-career personnel.

So imagine the surprise of Rep. Jim Himes (D-Conn.), 43, when he was mistaken for a college-aged intern on Thursday.

The lawmaker and father of two tweeted:

"Page on the Floor asked me if I was an intern. I thought she would then burst into tears, but told her it's best compliment I've gotten."

And while Himes is admittedly youthful looking, he is far from the youngest member of Congress: Rep. Aaron Schock (R-Ill.) turned 29 last month.
