Can I burp 100 times during the hour long presentation just to see how my professor will react?
That is a very strange thought you have. Are you serious? Are you sure your professor can take it?
I think its funny to burp just for the entertainment.
It is wrong to disrupt someone's presentation when others are trying to learn. You should skip it or have someone take notes for you.
Why? The presentation is just a waste of time anyway.
You may view it as a waste of time, but it could be important to your future career. You don't want to upset your professor, do you?
