After a few seconds of staring at his smile you realize what you have just done.
The salesman laughs. "Are you for real? How stupid can you get?!"
You start to panic, trying to move your body, but nothing moves. Your body is no longer yours.
"No! NO!" You scream as the salesman keeps laughing with signs of madness in his eyes. "You can't do this to me!"
"Oh, but that's the thing. I CAN".
Using your old body, he picks holds your head with your hands from the shelve. Totally helpless.
"I think I have just the place for you", he smiles again and puts your head in the same glass case the salesman's head was in.
"Have a nice time" he says as he closes the case and locks it from the outside.
"No need to breathe when your only a head. Am I right?" You look at him with fear, hoping he won't leave you there.
"For now you stay here, I have plans for you..." He leaves you alone in the room, locked in a glass case.
