I'm going to have to hand it to Cache Valley Daily for this one.
The Logan-based website had an April Fool's Day story that turned out to be quite a successful venture: "LDS Church to purchase Utah State University, rename it BYU-Logan." I saw some Twitter reaction Monday from some rush-to-judgement Aggies that was pretty funny, but this video passed on by a Twitter follower has to be the best.
This video posted on Facebook shows a young USU fan absolutely distraught over the prospect of having to be a BYU fan. (Sorry in advance, BYU fans, but at least appreciate the spirit of the video.)
