There's never short of humour going on around in lectures. Some lecturers are naturally funny, some are bizzarely boring, but even the boring ones make for good humour, situation allowing. Here are some of them

Lecturer was going around asking for opinions..
Class : *looking around trying to avoid eye contact*
Lecturer: *Points to 2 students who've been talking since the beginning of time*
You two,over there.. my old friend from thermo last year.. how're you going there?
Guy 1: *in heavy australian accent* yeah.How're u going mate?
Class: *Small laughter all around*
Lecturer: So wat do you reckon the answer is?
Guy 1: *still with heavy australian accent* yeah..i'll probably go for the 1000 Kelvin,man..
Lecturer: *chuckles to himself* "man".. Still havent changed,haven't you... Luke, right?
Guy 1: Yeah.. Michael (lecturer's first name) yeah?
Class: *bursts out in hysteric laughter*
Lecturer: *after laughter has ceased* Yeah, my wife calls me Dr.***** though..


In Fluid Dynamics lecture (which happens to be held in the Medical building)
*Halfway through the class, everyone concentrating*
*Guy walks in from front door,looking dazed. Looks at the overhead slides (which obviously are littered with mindnumbing equations), looks even more dazed, about to leave*
*Hesitates, turns back*
Guy: I'm sorry, is this Microbiology?
Class: *bursts out in hysteric laughter*
Guy: *leaves in a hurry*
Lecturer: *Scoffs* Microbiology? Who'd wanna take a subject like THAT??
Class: *even more hysteric laughter*

In a 9am Monday morning lecture..
*Guy walks in close to 5 minutes to 10*
*Lecturer and class watch in stunned silence as guy takes a seat*
Lecturer: And I think that's all we have for today..I'll see you guys next week.
Class: *hysteric laughter*

In the first lecture of subject, lecturer puts up recent years' students comments on his teaching..
" ****** *** is the worst lecturer. He wastes too much time, and tries too hard to be funny. Materials are covered poorly, and jokes about his wife are unneccesary. ***** *** (other lecturer in the subject) is a great lecturer. "
(That was literally on the board for everyone to see)
Lecturer: OK,I know I know this is bad.. but i promise not to joke about my wife anymore ok..
Class: *still laughing*
Lecturer: *Points to a student* Hey, you..wat's your name.. you were in this subject last year right?
Student: *shakes head, looks confused*
Lecturer: weren't you? Weren't you? Or was it in a different subject?
Student: I think it's probably summer course..
Lecturer: Oh yeah.. now i remember
Class: *sniggering away*
Lecturer: Hey don't blame me allright.. there's hundreds of you here.. Hell, sometimes I don't even remember how my wife looks like. Oh shit..
Class: *MANIACAL,HYSTERIC laughter*
