Alternates are really mysterious creatures, and not much is known about them. Besides the emergency PSA that aired 15 years ago regarding alternates, they seem to just be urban legends.

There have been a couple alternate reports throughout the years, but that's about where the mystery ends. Best we can do is gather the evidence ourselves!
