A professor was discussing the high glucose levels found in semen. A young female freshman raised her hand and asked, If I understand, youre saying there is a lot of glucose in male semen as in sugar? Thats correct, responded the professor, going on to add statistical information.

Raising her hand again, the girl asked, Then why doesnt it taste sweet? After a stunned silence, the whole class burst out laughing, the poor girls face turned bright red, and as she realized exactly what she had inadvertently said or rather implied, she picked up her books with out a word and walked out of class...

and never returned. However, as she was going out the door, the Professors reply was classic... Totally straight-faced he answered her question, It doesnt taste sweet because the taste-buds for sweetness are on the tip of your tongue and not the back of your throat.
