Imagine the following:

 You have just made it through your wedding ceremony

 and have stepped out on the front steps of the church.

 The photographer raises his camera.

  Following a family tradition, both of you hold white doves
 which you will release together.
 You and your new bride stand shoulder to shoulder with a dove in
 your hands as your friends and family eagerly wait.

 The photographer gives the signal and you and your bride open your
 hands toward the sky. Not a dry eye anywhere, the camera flashes;
 the moment is saved for eternity...
Now, you think the doves are going to poop, don't you?
