In a biology class, the professor was discussing the high
glucose levels found in semen which gives the sperm all the energy
for their journey.
A female freshman raised her hand and asked, "If I understand,
you're saying there is a lot of glucose, as in sugar, in
semen?"
"That's correct," responded the professor, going on to add
statistical info.
Raising her hand again, she 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, never to
return.
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. Have a good
day."
