Monday Joke

A professor was giving a talk about how much gluecose, as in sugar, is actually contained in human semen. one girl at the back of the class put her hand up and said,

" if it has so much sugar, then why doesnt it taste sweet?"

realising what she said, she got her books and ran out of the lecture theatre.

before she left, the professor quickly replied,

"because the taste buds for sweetness are located at the tip of your tounge, not at the back of your throat"...
