Banana in your arm pit????

Oh, our little Alicia is a creative one...  Trey was sick last week and she found the thermometer on an end table and stuck it under her arm and kept saying "tem-pa-too" (temperature) over and over again.  I didn't realize she knew what a thermometer was... but she had been to the Dr. two weeks before and obviously made the connection. Well, ever since she has become obsessed.  Every pen or crayon now goes under her arm as she exclaims "tem-pa-too!"  So this morning at breakfast she is nicely eating her banana and strawberries when she looks at me and SMASH - there goes the banana under her arm!  "Tem-pa-too! Tem-pa-too!"  I mean really, a banana???
