A radio station in Australia ran a phone in competition to find the most embarrassing moment in listeners lives.

 

The professor responded yes adding some statistical data. 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 turned bright red and as she realised exactly what she had inadvertently said, she picked up her books and without another word walked out of the class.

However as she was heading for the door the professors reply was a classic. 

Totally straight faced, he answered her question. "It doesn't taste sweet because the tastebuds for sweetness are on the tip of your tongue and not at the back of your throat." 🤣😂🤣😂
