Maybe gene-splicing (or zombie-making) is an elective? Or an online-only course?
Anyway, about the actual video... The Zombie Island of Dr. Ned is round one of Borderlands' downloadable content packs, set for release November 24. In this undead DLC, players help Dr. Ned try to cure victims of his research-gone-awry (which could potentially be something like gonorrhea if you pronounce it right). I assume that means shooting the bejeesus out of them, but I guess it could mean holding them down for a series of injections.
Now that sounds like something you'd do for extra credit in med school.
