Wow, and I thought I had good stories. Well, some of what I’m about to relate is fairly good, but nothing like some of the stuff so far. Us Dopers just attract fun, eh? 
Anyway, my first semester at RPI I took a course called Introduction to Methods of Theoretical Physics, with a professor with whom I’ve taken two other classes, and for whom I still do research. He is the absentminded professor, and I’ve never seen anyone work so many jokes into a physics lecture.
Some memorable quotes that I jotted down in my notebook:
“Oh. There’s a class here.”
(After several minutes of mixed up integrals) “There, aren’t I supposed to be proving that?”
(Discussing a math utility program) “I wasted at least half an hour over the fact that you gotta capitalize Pi.”
“I don’t like doing integrals. That’s why I make you do them.”
“Don’t do it now, it’ll prove me wrong.”
“Some of it will be nonsense, and some of it will be stuff I don’t teach.”
“So I’m going to ignore the 1/r for a minute … pause … forever.”
“This 4π is actually infinite. adds ~ to = sign”
Class: general well-if-you-say-so assent
“Well, you bought it!”
“It’s a rigid string.”
For some time he emphasized that the divergence of the radial vector is 3 (in cartesian coordinates). Over and over he told us we had to know that fact, and that it would be worth 50 points on the test. It was. Out of 820. And then there was the test we had on Talk Like A Pirate Day. Every problem related to pirates in some way while still being an actual physics problem. It was glorious.
He also illustrated certain optical polarizations by doing the trademark dances from Saturday Night Fever and Pulp Fiction.
The absolute kicker though was one day when he was discussing probability distributions. It hadn’t taken long for me to become one of the most vocal and noticed students in the course (I’m just friendly like that
), and so his example was, “Suppose I create a pit, and I throw Spatial Rift 47 in it.” Then he went on to describe, for 10 minutes, the distribution of my possible positions, as well as the probability that a rock he dropped from above would hit the top of my head.
Now here are two from Experimental Physics, same professor.
"Anytime you hook up a device, the inductor says, ‘Wooo … the current is changing!’ "
“I can see just fine. throws marker at garbage can, misses completely”
Now, I’m taking Quantum Physics with this guy, and I should emphasize again that in addition to all the funny stuff, he is an excellent teacher. Although, when teaching Physics for Archies (not actually called that, but that’s what it is), he instituted a practice in that course where if he had something off-topic to say he would go stand in a prearranged spot. He tried that in Quantum Physics, but it was quickly forgotten. Anyway, the few noteworthy things in Quantum Physics:
“So what we do is we look for points where the left side of the equation is equal to the right side.”
This was a legitimate comment, given the context, but I couldn’t help myself.
Me: “NO. WAY.” Laughter ensues.
Now, the last anecdote from this professor. He uses two overheads (such that their projections almost overlap) in QPhys, to be able to refer back to things; it’s easier for the students to follow his train of thought. One day he was indicating a substitution or something, but between two equations on opposite overheads. He drew a line starting on one overhead, and continued it on the other to the proper equation.
And then there’s my sociology professor. It is impossible to characterize this man in a single post, or indeed in any written form. You simply have to meet him to believe him. He is a 60something Brooklynite, and the things this man knows I’ll never understand whence he gets it all. He gets away with murder. A few weeks ago he went to a magic society conference in Las Vegas, and brought back pictures of himself being rather friendly with Supergirl. On the day we watched a video about a Peruvian healer who, at one point, used a ceremonial rattle, this professor brought in his own rattle and proceeded to use it for some time. Not a class session goes by when he himself does not wonder how he gets away with saying some of the things he says.
