This joke A mechanic who worked out of his home had a dog named Mace. Mace had a bad habit of eating all the grass on the mechanic's lawn, so the mechanic had to keep Mace inside. The grass eventually became overgrown. One day the mechanic was working on a car in the backyard and dropped his wrench, losing it in the tall grass. He couldn't find it for the life of him, so he decided to call it a day. That night, Mace escaped from the house and ate all the grass in the backyard. The next morning the mechanic went outside and saw his wrench glinting in the sunlight. Realizing what had happened he looked toward the heavens and proclaimed, "A grazing Mace, how sweet the hound, that saved a wrench for me!
