Stanford's secret twin

I wanna talk about a very important topic. STAN'S SECRET TWIN. It is a theory that has a lot of proof, is very well thought out, and is a very good theory. I think it plays a big role in Gravity Falls. Stan's twin's name is Stanley Pines. The videos below are about Stanley. I believe that Stanley and Standford Pines have both encountered  Bill Cipher at least once. Who knows? Maybe Stanley is the author.( Though it is not likely)
