From the opening lines of First Lady Michelle Obama's remarks this afternoon at Bradley Tech High School in Milwaukee, Wisconsin:

  MRS. OBAMA:  Yeah!  (Applause.)  Wow.  You guys, thank you so much.  (Applause.)  Oh, my goodness.  I am so thrilled, so honored to be here.      But let me just say one thing.  We just had a medical emergency over here, and I do not like to not regard that.  And I know things are warm, so if anybody is feeling hot, just sit down.  Just sit down.  (Laughter.)  Take your jackets off, gentlemen.  Take that tie off, relax yourself.  (Laughter and applause.)

Judging from Obama's remarks, it sounds like someone in the audience fainted.
