One of my favorite books, chock full of similes is:
So we discuss what similes are and see if we can identify them as we read the story. Then I asked the students to make self-portraits and write a simile to describe themselves. Now the one downside to teaching your students to be creative all the time is that it is impossible to turn it off. So even though I asked them to really draw themselves how they looked, the pics came out with a little bit of creative license taken.
I am shiny like the sun.
