Imagine that you are in a action movie and being chased by the bad guys. Your friend is driving the car and you are hanging in the car for dear life and you keep shouting:
You: I WILL DIE! I WILL DIE!
Friend: You're not gonna die! Trust me! JUST SING!
You: WHAT AM I GONNA SING?!
Friend: OUR THEME SONG BACK THEN!!!
You: *thinks about it for like 2 seconds* I CAN"T REMEMBER THE LYRICS!!
