I'm really not sure what to say about this one. Deadspin has the story.

In the video here (parts of which are NSFW due to penis photos), you'll see and hear all the strange messages Jenn Sterger received from someone she was led to believe was Brett Favre.

This is the evidence she told us about last February. Sadly, Jenn is still reluctant to talk on the record about the matter. Everything shown in the above video was acquired from a third party.
