Imagine / The fitness gram pacer test is a multistage AEROBIC capacity test that PROGRESSIVELY gets more difficult as it continues. The 20-meter pacer test will start in 30 seconds. Line up at the start. The running speed starts slowly, but gets faster after each minute when you hear this signal. *Bleeeeeep* A single lap should be completed each time you hear this sound. *Bleep* Remember to run in a strait line, and run as long as possible. The second time you fail to complete a lap before the sound, your test is over. The test will begin on the word start. On your marks. Get ready. Start.
A Imagination meme.
Imagination is SpongeBob forming a rainbow with his hands, from the episode where he explains imagination to an unimpressed Squidward. Captions start with "Imagine a world..." or simply "Imagination", and end with a dream, a fantasy or something nobody cares about. It's the meme for wishful thinking and sarcastic enthusiasm.
