A Tourist Visiting Ireland Notices Two Irish Laborers:

One laborer digs one-meter holes in a neat row while the other laborer immediately fills in the holes afterwards. They do this for a good portion of the morning but confuse the tourist who is watching them from the pub across the street.

The tourist walks over and kindly asks, "Why are you digging all these holes if he's just going to fill them right in?"

The Irishman says while digging, "Seamus the tree planter is off sick today".
