A group of students had a biology lab. As a part of this lab they were supposed to scrape some bacteria off their teeth with a toothpick and then examine it under the microscope.
But this one girl had some problems identifying her bacteria and asked the professor what they were.
"Those are sperm cells", replied the Professor.
