Monday bio lab-again

Bio lab again, and this time the experiment went quickly and flawlessly as usual for our dynamic duo. However, the lady in charge of this here lab enjoys wearing shirts advertising chocolate and making the entire lab class wait around until the end of the time period even when the experiment has been completed long ago. My partner in crime, Kim, is going crazy, she's about to freak, she has to go to work and she keeps babbling about hanging black lights on the wall (yeah I don't know either).
