So what if a female professor says "I like to eat semen" in class? That's my numerical method professor, she meant "salmon".
I remember an anecdote on a university:
One professor said that semen was full of sugar.
Then one woman, attendant, said: then, why it tastes salty?
Just after this she realized and blushed. While she was getting off class embarrased professor said: that's because swweet papilas are in front of tongue and salty ones are in the back....
