Dipper: "Grunkle Stan, I'm... I'm trans. I'm a girl."
Grunkle Stan: (look of realization comes over his face, puts his hands on her shoulders, looks her in the eye) "Dipper... do you know what this means?"
Stan: (shoves sign into the ground in front of the Mystery Shack)
Dipper: (now wearing girl clothes) "I don't know, Grunkle Stan-doesn't this seem kinda... manipulative?"
Stan: "How? The sign is perfectly clear!"
Dipper: (reading sign) "A portion of proceeds go to supporting trans girls?"
Stan: "Trans "girl"-singular, meaning you specifically! I pay for your food, don't I?"
Stan: "Listen, kid-it's my job to make money, and it's your job to stand there and look pretty!"
Dipper: (giggles and stims from gender euphoria)
Stan: "See that? I bribed you with compliments! THAT'S manipulation!" (Heads back inside)
Dipper: "...Hey!" (Starts chasing after him)
