TURN ON

Today i was in class trying to explain, "turn on the lights" and "turn off the lights" by using gestures with my fingers and the sound "boing". But of course mr. horny boy was in there and caught note of my gesture and made due with his own light switch. Saying, "its big, .... boing!" as he turned on his own switch with his finger. Oh my. I know i wont see the last of this ...
