The dictaphone

Vincent turned when his sister entered the living room, still in her panties, a large grin on her face, a strange device in her hand.

"What's that?" asked Vincent "Is it what you ordered?"
"I didn't order it... but I always wanted it." she smiled "THIS is ultimate power made real. A record in this thing and everything can become true. The letter didn't lie : this make wishes come true."

"Oh but it's not a joke... just look, brother, at what you missed!"
