Write something that could be passed off as a joke

I decided to write something that Cassidy might think was a bit of a fun joke that we could both laugh about later. I wrote "The clothes that Cassidy is currently wearing will transform into a sexy 1950s style satin pin up girl maid uniform when Cassidy comes to get the dishes.Cassidy's make up,nails and hair style will change so that they fit and complement her change of clothes. Cassidy will happily clean the house dressed and acting like a sexy pin up girl maid."

It took about 10 seconds for Cassidy to enter my room again. As if by magic Cassidy's clothes transformed into what I'd written and was thinking about. With a smile she quickly took the dirty dishes away and I can only imagine started cleaning the house.

To say that I was speechless was an understatement!
