"Li'l Ol' Me" is a song from the animated Disney show Gravity Falls. It features Gideon "Li'l Gideon" Gleeful displaying his "psychic" powers to a crowd of onlookers.
The song was performed by Gideon's voice actor, Thurop Van Orman.
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!]
[Wha--? How did he--?]
[Keep it going!]
You wish your son would call you more!
[I'm leaving everything to my cats!]
I sense that you've been here before!
[Oh, what gave it away?]
I'll read your mind if I'm able
Something tells me you're named Mabel
[How'd he do that?]
So welcome all ye... to the Tent of Telepathy
And thanks for visiting... widdle ol' me!
