UNDER THE MICROSCOPE

A teacher told his biology class about the common types of bacteria found in saliva. Frustrated by his students' apparent lack of interest, he told them they were about to undertake an experiment. After showing them pictures of what they could expect to find, he asked the students to take scrapings from inside their mouths and view them under the microscope. A female student examined her sample, but was unable to identify a particular type of cell, so she asked the teacher to have a look. He took a look through her microscope and then exclaimed: "Well, I never, that's a human sperm cell". Immediately, a male student who everyone knew as the girl's long-term boyfriend, shouted at the girl: "You bitch, you've never given me a blow job!" The girl broke down in tears and ran out of the room.
