Worst Joke ever

[Fifty bucks says you use it today]

A man has a dog called Mace, which he keeps in the house all the time, because all it does is eat grass.

He also has a favorite tool, his wrench, which he uses all the time.

One day He looses the wrench. He looks every where for it but can't find it.

The dog gets out, eats all his grass and there in the middle of the lawn is his wrench.

The man starts singing "A grazing Mace how sweet the hound, that saved a wrench for me".
