Just in case you were wondering how one makes a "muddy mud ball", I thought I would share the instructions I just heard my DD giving my DS.
"First you get a lot of dirt in your hand. Then you go and put your hands in the dog water. Then you throw the water and dirt between your hands and that's how you make a muddy mud ball!"
Now, I'll admit that my DD had a lovely, perfectly round ball of mud. My DS, however...not so much. Rather than having a little "muddy mud ball", as my daughter calls it, he himself is a muddy mud ball of sorts. The whole "throw the water and dirt between your hands" was apparently a little vague in its instructional detail. He's covered in mud and very upset that he doesn't have a muddy mud ball like his sister. As I type this, he is out chasing his sister around the yard in an attempt to get her muddy mud ball.
I'll deal with them in a little bit... first, however, I have to give the dogs some fresh water.
