Metro officials found themselves in the proverbial principal's office again Wednesday, and they insist that things are getting better. General Manager Richard Sarles and Chief Safety Officer James Dougherty testified on Capitol Hill in front of the National Capital region's congressional delegation and claimed that the transit system's culture of safety has turned itself around after the horrific June 2009 crash that killed nine people. The Post's Dana Hedgpeth reports on how “Metro has resolved more than 100 ‘corrective action items’ from the National Transportation Safety Board and the Federal Transit Administration.”

I watch a lot of television. I have for years. If I'm not doing something else, I always have it on. Even when I am doing something else, I tune in. So, when I heard that watching the tube can actually increase my risk of developing heart disease or diabetes, I was pretty freaked out. Coincidentally, the Discovery Fit & Health Channel has a new show designed for couch potatoes like me. The TV Column's Lisa de Moraes reports on the new show that pits out-of-shape 18- to 25-year-olds against "super-fit golden oldies" in an exercise competition.

It is most definitely intern season in D.C. The annual arrival of fresh-faced newbies in office buildings across the city is complete and they are impossible to ignore. That low-key happy hour spot you used to love? Ruined. That place you used to be able to dance without getting groped? Now a meat market. On the other hand, you do have someone to go buy your iced lattes when it's 1,000 degrees outside. Campus Overload's Jenna Johnson is The Post's de facto Intern Editor, and she's compiled a fun list of tweets about interns. She's also chatting today at 1 p.m. Sidenote: Sometime back, I was this intern.

Extra Bites

• Political advertising is typically not the classiest of programming, but some ads take the mud-slinging and stereotypes too far. Take, for example, this number, that attempts to paint a candidate for the U.S. House of Representatives as overly sympathetic to gang members. Slate's Dave Weigel calls it "the most offensive political ad ever, this hour."

• It hasn't been a great spell for the region's drivers. First, 700 people were cited in an HOV crackdown Tuesday. Then, a guy is accused of drunken sex at 85 mph while driving on the Beltway. Oy.

• If he were still alive, today would be Tupac's 40 birthday. This is my favorite Pac song of all time.
