On every fiftieth boot, the computer displays text written by Skrenta:
Elk Cloner: The program with a personality / It will get on all your disks / It will infiltrate your chips / Yes it's Cloner! / It will stick to you like glue / It will modify ram too / Send in the Cloner!

This technology went on to be used (at a smaller size) in laptops and computer servers everywhere.
