We went to visit my gramma today. She told us about how she worked
as a file clerk in the FBI and met J. Edgar Hoover. We watched the
Lawrence Welk show and I came up with the theory that all performers in
the show were actually Vulcans. Think about it. Do you they
ever let you see the tops of their ears? 
What
are they hiding? A recent episode of Enterprise talked about how
Vulcans visited Earth around the 30s and may have stayed for their whole
lifetime. You decide! (Yes, I’m just kidding.)
