Reply to comment by 54B3R_ in TIL: Sperms were thought to move by wiggling their tails side-to-side, like eels, for 350 years. But research shows that they roll as they move forward like a spinning top. by vect77
There's an urban legend about a morning biology lab in high school. The teacher had the students scrape their mouths and try to identify cells with a microscope, supposedly there's a few different types in the mouth.
One girl had blown her boyfriend before school and asked the teacher why her cell was different than everyone else's. The teacher looked and awkwardly said "That's a sperm cell."
