WHAT TO DO DURING SCIENCE CLASS:

O,what to do during Science class!
The possibilities are limitless:
There's drawing and yawning,
and portable chess.

There's dozing and dreaming,
and feeling confused.
There's humming and strumming,
and looking bemused.

You can stared at the clock.
You can hum a little song.
I've tried just about everything
to pass the time along.

BUT NOTHING WORKS!!!!!
