We’ve all heard these jokes, and perhaps we’ve finally got the answer.

This photo was taken on the Sliema promenade this morning.

Seven men look on and converse while another changes the bulb.

In a reaction on its Facebook page, Enemalta said the photo shows a number of Enemalta employees (it did not say how many, but we counted eight) and personnel from another authority that were attending a start of maintenance project brief on the Sliema promenade decorative lighting.

The Enemalta team then split in two gangs of two men each, one that would interact locally next to each pole and the other team at remote locations to carry out testing and switching along the entire promenade and at other remote locations.

Enemalta said it wanted to assure it customers that we give the necessary attention to both safety and efficiency at the place of work.
