You are walking in the city, when you happen to visit a strange shop that claimed to sell "unique" Barbie dolls. Skeptical, you come in.
When you enter, you hear a mystical version of the song "Barbie Girl". You then see a strange, short lady at the register. You noticed that head sort of looks like Barbie's. Blonde hair, lip, nose... all Barbie's qualities. "Fan?" You ask the lady.
"You could say that," she says.
"Let me guess. Your name is Barbie too?"
"Well actually, it's Barbara, but everyone calls me Barbie."
"Uh-huh. So do you get these dolls from Mattel?"
"Technically, yes. I used to work at Mattel, but they fired me due to the uniqueness of these dolls I made."
You look over the Barbie dolls. "They look the same to me."
"Well, I am giving them away cheaper than the average Barbie doll."
"Hm." You look around the Barbies. There are many of them. You finally pick one. "I'll take this one."
"Good." You give Barbara some money, then leave. "Have a great day!"
You get home, then place the Barbie on your bed. "Haven't had a Barbie doll before. I wonder what makes her appeal to younger girls." You then leave the doll to do other errands.
***********************
Night comes, and you are ready for bed. You get in, then grab your new Barbie doll in your hands, then go to sleep.
***********************
When you wake up in the morning, you see that something is amiss. Your bed seems bigger. A lot bigger. You then rub your forehead, but your hand feels... plastic. You look at your hand and see... That it is plastic! In fact, your whole body sans your head is plastic! Your head has somehow been implanted on the body of your recently-purchased Barbie doll! "I must be dreaming," you say to yourself.
"No, you're not," says a female voice similar to Barbara's.
"Barbara?" You call. You suddenly feel a hand pick you up. You look and see that it is YOUR hand! You then see your human body, then look up to see that on top of your body is the head of your Barbie doll!
She just smiles and says, "Actually, it's Barbie."
