Katy Perry was the guest picker on College GameDay for their first ever visit to Oxford, Mississippi today. Of course she picked Ole Miss, but it wasn't until she whipped out her corn dog that the Rebel fans got loud.

The running joke in the SEC is that LSU fans smell like corn dogs. I can confirm. Katy may not know much about college football, but hating LSU is a great place to start. Hotty Toddy.
