I'D LIKE TO PLAY SOMETHING WITH YOU TODAY.

IT'S A KIND OF A GAME, A GO-STOP-GO GAME.

AND SOME OF MY FRIENDS MADE A TAPE FOR ME-- A LITTLE TAPE LIKE THIS.

IT'S OF MUSIC, AND THEY PLAYED THE MUSIC AND THEN THEY STOPPED PLAYING, AND THEN THEY PLAYED IT AGAIN.

AND THEY SAID, "JUST LISTEN TO THE MUSIC "AND WHENEVER WE PLAY, YOU MOVE AROUND "AND WHENEVER WE STOP, YOU STOP.

AND THEN, WHEN WE PLAY AGAIN, YOU MOVE AROUND AGAIN."

SO LET'S JUST TRY THAT.

LET'S SEE IT I CAN WORK IT, NOW.

WHENEVER THE MUSIC PLAYS, WE'LL MOVE AROUND AND WHENEVER IT STOPS, WE'LL STOP.

( button clicks ) ( music playing ) ( music stops ) ( music playing ) ( music stops ) IT'S HARD, ISN'T IT?

( music playing ) ( music stops ) DID YOU STOP?

( music playing ) ( music stops ) ( music playing ) ( humming along to music ) ( music stops ) ( music playing; clicks machine off ) WELL, THERE IT IS; NOW, YOU GET THE IDEA.
