Blanca's veiws on teachers jokes!

Why do teachers make jokes? Do they do it to keep us awake, or do they actually think they are funny? With out saying any names I seem to have some "funny" teachers.... Some times I will be seating in class paying attention like I should and then they laugh... I honestly don't find their jokes funny... I mean they try so hard that the jokes are just dumb! They are suppose to be college professors, so stop cracking jokes and start teaching! Except you Sean Bernard, your jokes are actually funny =)
