Heard on the street...
Imagine a kid climbing up a steep hill towards a water slide that you ride head down (no it is not dangerous, you use a map and there is a bumper in the front). And as Dad fills the air with advice, little guy says, "Hey Dad, can you just let us die in silence, please????!"
Or another comment, "I can't believe that all these people like to streak down face first on the water slide."
Finally on all the different races and people of color in Hawaii, a great simile, "all the people here are like all the different colored beads on a multi-colored necklace.
