In the bustling habitat of the suburban jobsite, the seasoned electrician returns to his work van, distinguished by the unmistakable black leg-sleeve that has baffled observers for years. Much like a rare field marking on a migratory bird, its purpose remains unknown, yet it serves as a reliable identifier of the elder tradesman as he forages for tools in his natural environment. @chris kennedy #romexking

Well played, sir.
