Two Irishmen were working in the public works department. One would dig a hole and the other would follow behind him and fill the hole in.

After a while, one amazed onlooker said: “Why do you dig a hole, only to have your partner follow behind and fill it up again?”

The hole digger wiped his brow and sighed, “Well, I suppose it probably looks odd because we’re normally a three-person team. But today the lad who plants the trees called in sick.”
