Glucose in Semen

This actually happened at Harvard University in October of this year. In a
biology class, the professor was discussing the high glucose levels found
in semen.


A young female freshman raised her hand and asked, "If I understand,
you're saying there is a lot of glucose, as in sugar, in male semen?"


"That's correct," responded the professor, going on to add statistical
info.


Raising her hand again, the girl asked, "Then why doesn't it taste sweet?"


After a stunned silence, the whole class burst out laughing. The poor
girl's face turned bright red, and as she realized exactly what she had
inadvertently said, or rather implied, she picked up her books without a
word and walked out of class...and never returned. However, as she was
going out the door, the professor's reply was classic.... Totally
straight-faced he answered her question, "It doesn't taste sweet because
the taste-buds for sweetness are on the tip of your tongue and not the
back of your throat."
