SNL "Lazy Sunday" video and rivals

About a month ago, Saturday Night Live showed a new digital video short called "Lazy Sunday: The Chronicles of Narnia Rap". I watched it like 3 times on our Tivo before deleting it. Somehow it has caught on big time across the internet, and now others are making their own similar videos, sort of like the East vs West coast rap wars.

Here are the links to each of these hilarious videos:
1) Original SNL "Lazy Sunday"

2) West Coast "Lazy Monday"

3) Midwest "Lazy Muncie"
