or if you have any, I would listen to love. :)

I've heard
Save A Horse Ride A Cowboy
Save a drum beat of a drum and
Save Water, Shower with a friend.
but I want to know what they are called, so I can find a list of them or something, if a name, they still exist or could facilitate the search.
There are also some links to the lists of existing ones. : D
