You find you legs and arms getting longer, and your body and neck as well and you get harrier and then suddenly your shirt rips across the back and you grow a hump. Two humps! And you drop to your hands as they shift into pads and your feet do too.
Your clothing splits apart, dropping two the ground, and you spit on the ground on instinct. And then you eye the old woman at the potion booth.
She's looking at the empty bottle in her hand in with an expression of confusion and annoyance. "A camel? I thought this potion was suppose to turn people in to tractable marketable donkeys!" She looks at you hopefully. "Will you be a nice camel then and let me sell you?"
Nice camel! There's no such thing! And while you'd walk a mile for a cigarette, she doesn't look like she smokes.
You spit on her and manage to aim it straight down her open pie hole. Then you watch as she starts turning into a camel too.
