During their visit to the Tent of Telepathy in "The Hand That Rocks the Mabel," Dipper, Mabel and Soos watch Gideon perform the song, which successfully convinces Mabel he is a true psychic, while Dipper remains skeptical.
Oh, I can see, what others can't see
It ain't some sideshow trick, it's innate ability
Where others are blind, I am futurely inclined
And you too could see, if you was widdle ol' me!
Come on, everybody, rise up! I want y'all to keep it going!
(Crowd rises seemingly unintentionally)
DIPPER: Wha—? 'How did he—?
GIDEON: Keep it going!
You wish your son would call you more
OLD LADY: I'm leaving everything to my cats!
I sense that you've been here before
SHERIFF BLUBS: Oh, what gave it away?
DIPPER: Come on.
I'll read your mind if I'm able
Something tells me your name’s Mabel
MABEL: How'd he do that?
(Mabel is wearing a sweater with her name on it)
So welcome all ye... to the Tent of Telepathy
And thanks for visiting... widdle ol' me!
