| A biology professor is discussing the high glucose levels found in human semen. A female student raises her hand and says, "Glucose is raw sugar. Why doesn`t it taste sweet?" The whole class starts laughing, and as the girl realizes what she`s said, her face turns bright red, and she picks up her books and starts to run out of class. As she`s going out the door, the professor says, "It doesn`t taste sweet because the taste buds for sweetness are on the tip of your tongue, and not on the back of your throat." |
