I used to work in the urology dept. Our job, of course, involved everything that had to do with to your most private parts, including vasectomies. One day, one of the biomedical techs came around asking for the semen ultrasound so she could inspect it. I politely told her that we didn’t have a semen ultrasound, the semen samples were turned over to lab for evaluation. She should go to the lab for the semen ultrasound. After about 20 minutes or so the tech came back to me and told me she found it. Curious, I was thinking what the heck is she talking about. She brought me over to the “Siemen” (brand) ultrasound that we use to do prostate biopsies with. I cracked up laughing. Hey, we were working in urology after all, when she said “Siemen,” I thought she meant “semen.” Duh !!!
