And the Charade Begins

Unlike Audrey Hepburn in the movie Charade, my own charade involves the lab coat costume I recently acquired (ok, its a real lab coat - and i am a real teacher - it just feels foreign). And my leading character is sadly not Cary Grant - but a badly behaved fifth grader (the second and third graders make much better leads). Anyhow, I will try and stay a day ahead of them. Yesterday was the circulatory system, and the chicken heart I brought in was greeted with ooh's and ah's (for the record I'm in the "ewey" category).
