Pelosi stressing out? Asks protestors: "Can we drill your brains?"

Reported today in Politico (underlining mine):

House Democratic leaders and protesters waving McCain signs had a war of words Tuesday at a press event outside an old train station. The demonstrators interrupted House Speaker Nancy Pelosi with chants of “Drill here! Drill now!”

Pelosi paused and asked the group, “Right here?”

Seeming to enjoy the back and forth, she followed with another question: “Can we drill your brains?”

Why so angry, madame speaker?

(And for someone who supports abortion, which literally can include the drilling of infant heads, that's not the kind of thing you want to be saying in public.)
