Saw this on Deadspin today. Apparently, two guys named Cuevas are big Brett Favre fans, and have put together a song about their hero called "The Ballad of Brett Favre: I Will If You Let Me."
It's a country tune (what else?) and the first 30 seconds of this clip are silent.
No mention of the Vikings in this song. Don't know if that's a good thing or a bad thing. Enjoy.
