I heard the following story from my father James Keenan (age 54 Yrs) a native of Mountmellick Laoighis.
About three years ago in Mountmellick a man was churning. While he was churning another man came in and lit his pipe and began to smoke. After a while he went out. The man was churning for two hours before any butter came. When it came it went away again. He was churning for about six hours altogether before any butter came at all. After a long time the man that was churning made out that it was the man that went in and lit his pipe and went out without taking a dash at the churn that took the butter. From that time on whenever a man lit his pipe while churning was going on he made him take a turn of the dash.
