Worked for me!

This one time I was watching this funny TV show. Can't really remember it, but it was really funny Then I had an idea for a dream vacation I mean, I had the spread, okay? The beach, the hotel then I wrote all of this down Wrote it all down, really wrote it, like five pages. Lost it!

Too sweet to be sour, too nice to be mean

YOU BOTH IT!!
