Early 70's when I was about 20. My Company had a contract with the Government to maintain and repair office equipment. Sometimes it would be a faulty cord end or something else that required crawling under a desk or work station. Days of short skirts and an Air Conditioning system that would not keep up on hot days. A few girls would go commando. I would get a BONER

and have to sit in front of a Machine and 'check it out' for proper operation(excuse), until my Boner would subside.
