Demi Lovato can't say no

"Um, Demi," I said, eager to take advantage of her hypnotized state. "When I say 'Dumb Demi', you will go back into this trance. Got it?"

"Yes." Demi said in a mindless voice.

"When I snap my fingers, you will awaken and not be able to refuse any request I make, even if you really want to. You can not deny me anything I want from you, no matter how degrading it may be."

I woke her. She blinked twice back into reality.

"What happened?" she asked.

"You hypnotized me, remember?" I said. "Now, talk like a bratty toddler."

"Um, okay," Demi said. "Demi tawk wike a toddler."

Then she realized what she was doing. "Demi not know why Demi tawking wike this. Demi want it to stawp!"

I laughed at my roommate's humiliation.
