The coach of the college baseball team, Mike Buck, was checking the residence grounds to be certain his players were in by curfew. Suddenly, he heard a loud crash and turned to catch a glimpse of a man running into the residence. Buck thought it was his star right-handed pitcher, James Macullah, but he couldn't be sure. Buck went to James' room and opened the door. James stood in the middle of the room, his right leg in his pants and his left leg out. James, looking at the wristwatch on his left arm said, "I heard a loud crash and was getting dressed to see what happened", he stammered. "Forget the bull," said Buck, "I'm certain it was you who just ran in here. For that little caper, you won't be playing tomorrow." How could Buck be so certain it was James who had been out after curfew?
