Time
A gentleman was moving from one house to another, a couple streets away. Observing the care-free way in which the moving crew yanked his furniture about, he decided to move his prized grandfather's clock himself.Taking the antique in his arms he started for the new house. But the clock was almost as tall as its owner, and he had to put it down every few feet and rest his arms.
After half an hour of these exertions he was just about there, when one of the locals happened to walk out of the corner bar. Watching the man with the clock for a few moments he walked up to him and said in an unsteady voice, "Mister, can I ask you a question?"
"What is it?" demanded the man.
"Why on earth don't you carry a watch?"
