This is true. Someone I know was trying to use my computer (they didn't have permission to do that, but that isn't really the point), but the computer wasn't on, so they took one of my 3.5" floppy disks and put it in the slot, and then pushed the button to eject the disk so that it came out, and put the disk back in, and take it back out, and kept repeating that until I asked her what she was doing. She said, "I put the disk in and pushed the START DISK button, and it just comes right back out! Why is that?"
