the third man

An old joke amongst friends fondly retold for the benefit of one special supper guest.

A tourist is watching two workers at the side of the road, one of the workers digs a hole and after a couple of minutes the other fills it up with the turf that's just been uprooted. This goes on for about an hour and the tourist whilst amused can't figure out exactly what these two guys are up too, eventually decides that he will ask them, what they are doing.

The workers reply that they generally work in a team of three but that the third worker who plants the trees is off sick.

One of my great corporate fears is walking into an interview and being asked to tell a joke by some maverick HR manager, if I ever get asked to, this would be a good one and would guarentee me making the shortlist.
