The man was really impressed with their hard work, but he was completely dumbfounded as to what they were doing.
Finally, he approached the workers and asked, “I appreciate how hard you are both working, but what the heck are you doing? It seems that one of you digs a hole, and then the other one immediately fills it back up again”.
