Obviously Stan knows all about the mysterious things going on in Gravity Falls, several times he does little things that shows he knows what the kids are getting into, for example in "Carpet Diem" he acts as if he doesn't recognise the room, yet you see him TAKE THE GLASSES on the end table (which means those glasses are probably like the carpet) and at the end of the episode, why is he outside in the middle of the night?

Also, the time in "The Deep End" Stan must have known about the merman - when he tried to break into the pool at night why did he cut a hole in the fence big enough for the golf cart to get through? (while he could have just jumped the fence if he were there only for the lawnchare)

In almost every episode Stan does something to help the kids in whatever mystery they are in, it cant be a coinsedence!
