Taylor Swift has a ton of fans who absolutely adore her, but there are also some people who wish the famous, country singer would just shut up already. T-Swift fan or not, this guy who attended her concert is clearly a little nutty. 

According to Gossip Pop, a man was arrested this past Saturday at Taylor's Pittsburgh concert for holding a not-so loving sign. A couple days prior to the concert, Joseph Jackson- the crazy man- allegedly threatened Swift on Facebook. Once the police saw his "Taylor Swift is Satan" sign at her concert, they put two and two together.

Jackson reportedly told the police, "Taylor Swift is Satan and that 6,000 years is six days and death comes on the sixth day, so Taylor Swift is in danger."  With that being said, he was taken into custody and forced to undergo mental evaluation. Probably a good idea. Moral of the story:  people are just crazy.
