As someone who pirated lots of floppy disks and cassettes in my day, I'm not suprised.

I can't believe the mouse turned into a sheep after 58 clones

Star Trek: The Next Generation, season 2, episode 18. Up the Long Ladder. Dr. Polaski identified this very problem on a planet full of cloned survivors in a colony on a planet which was composed of clones of the 5 survivors of the ship that crashed there hundreds of years earlier. It's called "replicative fading".

"Multiplicity" was correct?! A clone of a clone is like a Xerox copy? It's never quite as sharp as its predecessor.

Wow, biologists discovered the point when they need to stop cloning from the original long before Hollywood producers did.

Mr Petrov, I have been watching your videos for a long time. (In Web years, that is.) I enjoy nearly every episode; some are too disturbing. The wide range of topics, seasoned with your dryly humorous remarks make a treat for the mind for this old geek. Occasionally a show of yours kicks my head into the back yard, then I have to fumble stumble around to find it. This is one of those shows. Thank you.

The Asgard had a similar problem in Stargate: SG1.

4:20 the stock footage is not a mouse, it's a (very cute) domestic rat.

I guess that explains why there wasn’t a Clone War II
